<br /><br />
With the very high resolution topographic digital terrain data from LRO it is possible to create or recreate any illumination for any piece of the lunar surface. Despite that capability it is personally wondrous to come across at the telescope such spectacular lighting as Claude captured here. Hartmann and Kuiper called this two-ring basin the Basin Near Schiller when they first described it in the early 1960s, but the quasi-official name is the Schiller-Zucchius Basin. Both names tell you that it is near Schiller, the almost cigar-snapped crater at center right. The main basin rim (335 km in diameter) is best displayed to the left of Schiller, where it curves around towards Zucchius, whose near rim only is illuminated at the terminator. At the snout end of Schiller a surprisingly strong shadow is cast by the very low basin rim to the north. Both sides of the 175 km wide inner basin ring are visible, and what this lighting shows very well is the rounded drop off of an inner, inner ring. Three small hills inside the inner, inner ring are usually inconspicuous, but this shadow-magnification reveals them clearly. The SZB is an old basin, and while there may be ancient basalts in it, the visible smooth material is largely fluidized ejecta from the formation of the Orientale Basin. <br /><br />

<br /><br />
We often have friends, family and kids over to take their first look at the moon through a quality telescope. We use a 4" refractor for two reasons. First. almost everyone instinctively understands which end of the scope to look through, which is definitely not the case with a Newtonian or even an SCT like a Celestron 8. Second, many first time viewer are surprised by the brightness that hits their eye, and they become nervous about damaging their vision. The smaller aperture does a good job of reducing the moonlight to tolerable levels. And we use a high quality plossl (eyepiece) from 24mm to 32mm, since they are easy to look through and easy to focus for the novice observer.<br /><br />
So, when a first time observers looks at the moon through a quality scope, three things inevitably occur: everyone says, &quot;Wow!" a couple of times, they quietly realize they have no idea what they are looking at, and they always ask where did the moon landings occur. Here’s where this map, which is uploaded onto my iPad. comes in handy. Since the map is made from a prime focus photograph thorough this same scope, the scale is pretty close to what they are seeing through the eyepiece. I hold the iPad, and then ask them to start identifying what they see through the scope with what’s on the map. Their ability to name the features they are seeing is nice experience for them and us. After identifying the major maria, it is an easy segue into talking about how the maria were formed, and why the molten magma migrated to the nearside of the Moon facing Earth. I also like to briefly explain the age differences between Tycho (108 million years) and Copernicus (800 million years) in the contest of their rays. Astronomy outreach is an important part of being an amateur astronomer.. our fondest hope is that the twenty minutes we spend with a first time observer will lead them onto a new path of discovery.<br /><br />

<br /><br />
This is a fascinating image because of the way it has been processed. The mountains are full of angular roughness but the maria look like they have been filtered to smooth out details, as if the lava flows were very fluid and froze with a nice smooth surface. This treatment emphasizes the broad surfaces of the maria rather than their details, and makes the mountains stand out as sharply different terrains. One thing that pops out is a broad swell east of Aristillus and pushing up against the south part of the Caucasus Mountains. LRO QuickMap [http://bit.ly/1fSLcNE shows] that this swell rises about 400 m above the mare to the west, and is partly made of the older lavas cut by the Theaetetus Rilles, but includes Imbrium lavas too. Many swells face up against individual mountains or mountain walls, but I don't know why.<br /><br />

Mike's wonderful new image of Tranquillitatis makes the Lamont region look like the gnarled hand of a hard worker. Narrow and wide ridges cause the mare surface to undulate at different wavelengths, a complexity that will evaporate with a slightly higher illumination into a flat dark lava plain. For me, the most interesting part of the image - meaning there is something seldom seen to enjoy and ponder - is the bottom half. In particular, the segmented broad ridge that crosses the south end of the mare between [http://bit.ly/1i1HTlQ Censorinus B and the Apollo 11 landing area]. At some places this is seen (courtesy of LRO QuickMap) to be a fault, whose north side rises 100-150 m. The linear tectonic feature is roughly continuous with the Guttenberg Rilles family, although the individual rilles are at a different angle. This family and the mare tectonic feature are radial to the center of Imbrium, as are the straight ridge from Maskelyne to Lamont, the ridge that crosses northern Lamont, and the Cauchy Fault. The basin's formation must have had some structural influence on the orientation of the ridges and fractures.<br /><br />

I am watching the first minutes of COSMOS and remembering that the nearest cosmic neighbor is our Moon. <br />
There is an infinity of galaxies to explore, not to mention multiverse bubbles, but nowhere in the cosmos can <br />
our personal exploration see more details than at the Moon. Damian's excellent image shows a detail that<br />
often is not visible, and rarely captured as clearly. Humboldt is a glorious large crater that everyone would <br />
know if it were easily visible from Earth. We see it obliquely, looking across a rille-cracked floor, to the dark <br />
lavas of Mare Australe to the southeast. But now Neil Tyson has just finished with his story of being hosted <br />
by Carl Sagan, and its time for me to finish too.<br />

[https://the-moon.us/wiki/Mare_Undarum Mare Undarum]; is there a more forgettable name or place on the Moon? I took this photo with low expectations. After all what of interest could be there? Then I noticed the concentric crater, Apollonius N. I had been aware of its location while preparing a [http://www2.lpod.org/wiki/July_28,_2013 paper] for last year’s ALCON convention. Then it dawned on me that other concentrics were in the general area. I began searching, and sure enough, the concentric craters near Schubert N and by Dubyago were also visible on the same frame. Then the obvious concentric crater Firmicus C popped into view. It had not been on my list of craters for the ALCON presentation; how did I miss it? Closer scrutiny of the area along with some internet surfing, plus a little reviewing of the LROC ACT-REACT QuickMap revealed two other possible concentric craters which are marked by arrows with question marks. Wow! There are four concentric craters in a single high-resolution frame plus two other possible concentric craters. Mare Undarum has turned out to be quite an interesting place after all. Concentric craters have much shallower depths than normal craters of similar size and appear to have been modified by pressures under the surface that elevated their floors and created the inner rim or toroid. Close scrutiny of the QuickMap hints that other small craters in the area also have had their original depths and interiors modified without the development of the inner toroid. It makes me wonder if concentric craters are only part of a spectrum of craters of similar size and age that were modified by volcanic intrusion some time after their formation.<br /><br />

I learned in the latest edition of the ever-interesting <em>Lunar Section Circular</em> from the British Astronomical Association of a new MOOC called <em>Moons</em>. For those not into recent educational innovations, MOOCs are massive open online courses, typically with thousands to tens of thousands of students scattered all around the globe. The lectures are presented as weekly videos and there are activities to complete and discussions to participate in, all online. Most MOOCs, like this one, are free, and each student decides how much effort to invest. For most MOOCs only 10-20% of the starters complete everything to earn a certificate of completion. But MOOCs are not a failure for they have allowed millions of students to access and follow as much as they want some of the best courses and teachers in the world. My old friend Dave Rothery has put together this Open University MOOC which will cover not just our favorite moon, the Moon itself, but consider many of the 160 odd others. The 8-week course starting March 17 is said to be for beginners, but considering the range of places and processes represented there will be things for everyone to learn.

A new contributor to LPOD appears with an excellent image of [https://the-moon.us/wiki/Goclenius Goclenius]. The lighting suggests that its floor rises towards the rille that hugs the upper right crater wall, but the LRO [http://bit.ly/1eU7Una QuickMap] topographic tool shows exactly the opposite. The pie-shaped part of the floor is about level, but once the upper diagonal rille is crossed the land slopes about 140 m to the east/right, and at the wall rille, it plunges down another 250 m. Our eyes, or at least mine, are often fooled by lighting, and need measured topography to really understand what is going on; fortunately, we now have it. The mare surface east of Goclenius undulates with mare ridges, buried crater rims, and slight swells tens of meter high. One more odd thing - look at the center of [https://the-moon.us/wiki/Magelhaens Magelhaens], at lower left. Small, slightly bright points looks like a smallpox vaccine scar. LRO's higher resolution shows the same thing. Because it is in the center of the crater it could be the just slightly lava-covered tops of a cluster of central peaks, but it isn't completely convincing that that is what it is.<br /><br />

Rays are perhaps the least studied of all classes of lunar features. There are important studies of their formation mechanisms and how they age over time, but I am not aware of investigations of their patterns. For example, how should ray patterns be mapped - how could the differences between Tycho's rather bold rays be quantitatively compared to the somewhat wispy rays of Copernicus? Part of the difficulty is in developing a processing technique that clearly separates rays from other features. Max has been experimenting with his color images and has produced this colorful image that effectively defines the main rays of Tycho. In his [http://maximusphotography.wordpress.com/2014/03/03/tycho/ blog] Max describes his processing and some of his observations. He notes how well the image documents the zone of avoidance to the west, showing that the crater-forming projectile came from that direction. It is also amazing that one prominent ray to Tycho's southwest is neither radial nor tangent to the crater. A number of bright ray clots occur, especially the large one called [https://the-moon.us/wiki/Cassini%27s_Bright_Spot Cassini's Bright Spot] northeast of Tycho. Fresh impact craters show up as yellowish spots, but the dark rays of [http://www2.lpod.org/wiki/October_1,_2012 Buch B] look like spectacular red fireworks near the right center margin below the dark line of missing data. Also showing as red are the three other dark splotches of Maurolycus A and F and Walther A. Color mapping definitely reveals features that are otherwise difficult to detect.<br /><br />

<td>Basin rims intrigue me. I want to understand why they usually are not tall and continuous as fresh crater rims are. Here, the question is why is the western rim of the Crisium Basin broken? North and south of here most of Crisium's rim is continuous. Here in the west it looks like a vehicle could be driven from the outside to the inside on level ground where the two sloping promontories almost touch. (With LRO [http://bit.ly/1klSlYL QuickMap] you can see that there is one ridge to drive over.) The two large, ruined craters with flat floors postdate the formation of the basin (they would have been destroyed if they were first) and they do cut into the western rim. But with a basin-wide [http://bit.ly/NHIaQk perspective] we are reminded that the eastern side of the basin is even more open, some of the evidence that Crisium formed from an oblique impact. So, perhaps there were two processes at work here. An oblique impact with the projectile coming from the west formed a basin with low east and west rims, and two later impacts carved away a gap through the already low western rim segment. On another topic, notice the slightly elevated and fractured terrain just west of the rim, and northwest of Yerkes. This looks like the interior of a floor fractured crater, minus the crater. Similar fracturing is inside Lick. Are the few low hills nearby remnants of a rim, or is this a case of floor-fracturing not inside a crater?<br /><br />

[https://the-moon.us/wiki/Julius_Caesar Julius Caesar] - the 90 km wide crater, not the Roman general and destroyer of a republic - is about 500 km from the Apennine Front, the rim of the Imbrium impact basin. The crater and the area surrounding it were blasted, scoured, pelted and pasted by debris falling from the sky and rushing across the surface. Caesar, its F and P, [https://the-moon.us/wiki/Boscovich Boscovich] and a few other features here are pre-Imbrium craters that survived, barely. Other than the much younger small impacts, most of the other crateriform structures - like Boscovich P and perhaps E - are probably Imbrium secondary craters. The line of multiple overlapping craters - Boscovich P - is characteristic of basin secondaries, as is its radial alignment with Imbrium. The dark mare lava in Boscovich, Caesar and a few other low spots was erupted much later. The slathering of the surface with the pasty ejecta mush created undulating terrain with small groves and hills. At Boscovich E it looks like course ejecta surged along the surface and spilled into and then out of the crater. Near the bottom left corner the arrow points to a small dome-like feature. This may be a volcanic dome fed by magma rising from depth, but it might also be some pre-existing hill plastered and smoothed by the ejecta flow. Finally note the delicate straight rille indicated by the three arrowheads. At first I thought this was a seam boundary for a mosaic, but it changes its width and character along strike. And then I thought I've seen this before! It was discovered by K.C. Pau, and I thought there was an LPOD of it but I couldn't find it. I did find one of K.C.'s that confirms it with no doubt. This is Pau's Rille.<br /><br />

<br /><br />
In 1942, Walter Haas, the founder of amateur planetary observing in the USA, published a paper called, <em>[http://adsabs.harvard.edu/full/1942JRASC..36..237H Does Anything Ever Happen on the Moon?]</em> Haas was referring mostly to what became known as transient lunar phenomena; hazes, obscurations, new features and flashes on the Moon. None of those TLPs has been documented to have produced a real change on the Moon, except for flashes. Since the Lunar Reconnaissance Orbiter has been circling the Moon a number of new impact craters have been discovered that are less than 3 years old. I believe that one had also been observed from Earth as a flash of light. Now, José María Madiedo, a professor from the University of Huelva in Spain, has succeeded in capturing the brightest lunar flash ever documented, and he produced the video above showing the footage and offering an explanation and a high quality animation. This was not a lucky random catch of a flash, for Prof. Madiedo had set up a network on robotic telescopes across southern Spain for this and other astronomical work. A paper just published (and freely [http://mnras.oxfordjournals.org/content/early/2014/02/19/mnras.stu083.full downloadable]) in the <em>Monthly Notices of the Royal Astronomical Society</em> states that the projectile was 400 kg in mass and travelled at 61,000 km/hr. The crater created is estimated to be 50 m in diameter, big enough to be well seen when LRO images the area. <em>[https://www.sciencenews.org/blog/science-ticker/lunar-asteroid-impact-caught-video Science News]</em> has stills from the flash and 8 seconds of brightness decay. Congratulations to Prof. Madiedo and his team for demonstrating that things still do happen on the Moon. <br /><br />

<br /><br />
This is LPOD, so where is the Moon in this image? It is inferred. This is a still captured from an hour-long BBC-Scotland science video from 2011 that I have only just seen. Called <em>Do We Really Need the Moon?</em>, the video is typical BBC, with superb graphics and animations, a passionate scientist narrator, and only slightly-muted bombastic music. This reminds me of the great science videos done by Carl Sagan and more recently Brian Cox, for we see the narrator standing in desolate but awesomely beautiful places, feet wide apart, staring down the universe. The narrator here is Dr Maggie Aderin-Pocock, a space scientist and self-styled lunar fanatic who has just replaced Patrick Moore on <em>[http://www.bbc.co.uk/programmes/b006mk7h The Sky at Night]</em> TV program. The Moon video focuses entirely on the Moon's gravity affects on the Earth, rather than the Moon itself. The two main topics are the Moon's role in producing tides and in stabilizing the Earth's tilt. Starting with remarkable video of an onrushing tidal bore in a Scottish loch the story turns back 4 billion years when the Moon was 20 times closer to Earth and the tides were vastly more extreme. The image above shows how those ancient tides would submerge New York City, and animations depict the flooding of low areas all over Earth. George Wetherill was the first to describe how the Moon limits the range of tilt of the Earth. This video talks excitedly of how a billion years from now the Moon will be so far away that the Earth could tilt over on its axis causing climate catastrophes. Overall, I found the narration too intense and the video too long - provoking a siesta before the end. But the animations are first rate and would be excellent additions to talks to schools and public audiences. And we should all be grateful anytime the Moon is in front of the public for an hour.<br /><br />

<em>image by [mailto:beanzhere@hotmail.com Kerryn Murphy], Perth, Western Australia</em><br /><br />
<br /><br />
When I first looked at Kerryn's image my thought was that I would have to photoshop Saturn to enhance its visibility. But then I realized that the message here is that the Moon is a lot brighter than Saturn. I know that, but an image is a more dramatic way to absorb that than just saying the apparent magnitude numbers. The full Moon's apparent magnitude is -13, and Saturn is +1. This 14 magnitude difference means that the full Moon is about 400,000 times brighter than Saturn. That is not the impression in this image. Using the histogram tool in <em>Photoshop,</em> I find that the planet (not including rings or space) of Saturn has a value of 48 out of the 256 shades of grey scale, whereas the entirety of the Moon imaged here is 120, with bright craters going up to 210. So, pixel to pixel, the Moon is about 120/48 = 2.5 times brighter than Saturn, and the bright parts of the Moon are about 4 times brighter. But the reason the full Moon is really much brighter than Saturn is that the Moon occupies a much larger area in the sky than does Saturn (about 2000 times greater angular size). Another piece of information from Kerryn's color image is that Saturn is bluer than the Moon. I also think there is a hint of yellow but that may just be because I remember that Saturn is yellow in the eyepiece. <br /><br />

I've been doing a study on lunar phases and this is my latest sketch. It's a photo of the sketch from last night after wrapping up my observing session. No adjustments have been made to the sketch other than cropping the lower blank portion of the paper. My phase sketches used to take close to two hours at the eyepiece to complete. I've been building up my endurance to 3-4 hours for a single sketch to include more detail. Obviously, the terminator is drawn first to &quot;freeze&quot; the time stamp on the phase. Then I work my way across the disk at a more leisurely pace, moving my observing chair and stool gradually as the session progresses. Total eyepiece/sketch time is just over four hours on this one.<br /><br />
<br /><br />
<em>[mailto:erikarix1@gmail.com Erika Rix]</em><br /><br />
<strong>Admission by CAW:</strong> I did adjust Erika's submission by making the sky uniformly dark (it had a cross-image tonal variation due to the photographic copying), and I flipped it so it has north up and east to the right, as we see it in the sky but not not how Erika sketched it - artists show exactly what they see; I removed the effects of the telescope optics. <br /><br />
<br /><br />
<strong>Technical Details</strong><br /><br />
I used a 102mm f/9.8 refractor on an LXD75 mount, 20mm eyepiece setting on my Hyperion zoom, and a 13% T Moon filter to help with contrast. The media is black Strathmore Artagain paper (60 lb., 160 g/m2), white charcoal pencil, black charcoal pencil, white Conte' crayon, white Conte' pastel pencil, black Conte' color pencil,and a blending stump for the maria. I used a circular 6-inch protractor to outline the lunar disk.<br /><br />

When I see a dawn Moon from the city, I keep thinking about the amount of people who follow in your daily routine without realizing it. <br />
It is possible that this is one of the most beautiful moments of the night and few people have bothered to take 10 minutes to watch this show. <br /><br />
<br /><br />
A friend asked me how far were the buildings? How can you to photograph such large moons? <br /><br />
I gave all the technical data, but the secret is: <br /><br />
<br /><br />
As close as possible to the Moon and get away as possible from Earth. <br /><br />

It seems a utopia, but we who have photographed with telescopes will know what I mean.<br /><br />

next to the terminator, also very well observable at the eyepiece, despite the rather poor seeing conditions. Mare Crisium is perhaps the best place<br />
on the Moon to look for a nearly horizontal view of mountains coming up from the &quot;sea&quot;. This sea is actually four times as wide as the [http://en.wikipedia.org/wiki/Black_Sea Black Sea], my<br />

<br /><br />
To honor the 541st birthday of Nicolaus Copernicus on the 19th of February, 2014 I decided to sculpt a clay relief model of Copernicus crater. I've been working on the model for a little over a month in order to capture as much detail as possible. I've drawn extensively from the LRO Lunar Orbiter Laser Altimeter (LOLA) elevation data set presented as a color scale to interpret general structural details, but I've also reviewed images from <em>The Kaguya Lunar Atlas</em> by Shirao and Wood, as well as Apollo and LRO and Lunar Orbiter images. The model is 20&quot;x 20&quot; and Copernicus's rim is roughly 9&quot; across. That works out to a scale of one inch equals 10 kilometers. The depth of the model is about 0.4&quot; from rim crest to floor, so the thickness of the clay layer is about 0.250&quot; thick with about another 0.150&quot; built up to form the glacis and highest rims. I took two photos of the model, offset left and right from a baseline so if you can cross your eyes slightly, you can get the two images to merge into a single stereographic view. <br /><br />
<br /><br />
The complex crater Copernicus was created about 800 million years ago when an impactor about 1.5 km in diameter, slammed into the western quadrant of the Moon on the eastern edge of Oceanus Procellarum and the southern rim of Mare Imbrium. Though the shape has been described as roughly hexagonal, it is 93 kilometers in diameter measured from rim to rim. It's depth is 3.8 km from rim to floor, a broad 30 km wide glacis surrounds the rim, fanning out onto the mare. Massive slump terraces cascade down onto an impact melt splashed floor whose southern margins are hilly and hummocky. The northeast quadrant is a relatively smooth melt sheet. The slightly offset central peaks are about a kilometer high. Ejected impact melt has pooled on the northern and southern terraces, flowing down the crater walls to the floor. Ejecta were also flung onto the surrounding mare, where the impact created herringbone patterns when it decelerated. Rays of pulverized rock were launched into long arcing trajectories that reached hundreds of kilometers down range. I noted that the LOLA data as well as orbiter images indicate that the southern wall is almost twice as wide as the northern wall and that the central peaks are also offset along this same axis. This seems to suggest that the impactor was traveling from the north to the south when it hit the Moon, although the angle was not so shallow as to create the classic butterfly pattern of rays as seen in craters like Proclus.<br /><br />

<br /><br />
For ten years we lived in North Dakota. We were in the flat eastern section with little scenery except for the sky. Sunsets were often wonderful, and the galaxy could be glimpsed from within town, but it was auroras that taught me how the sky could interact with humans. Not the little red or green northern glows, but the sky-filling displays of pulsating colors. On stepping innocently outside and looking up at such a phantasmagoria, the first response was fear. What in the world is going on? It is unnatural to see the entire sky awash with curtains of color that rise and fall and move sideways, colors always shifting. The sky should be stable, with stars and planets in their places, moving only on a nightly basis, delightfully enlivened by an occasional shooting star. But the sky should not be everywhere dancing a mad fandango. It is easy to understand why earlier peoples considered that the auroral gymnastics must be due to a deity, one who was upset. Mohamed's image of a perfect lunar halo evokes a little of that unease, especially for a [http://www.telegraph.co.uk/news/worldnews/northamerica/usa/10640518/One-in-four-Americans-do-not-know-the-Earth-circles-the-Sun.html scientifically primitive population]. Many observant people have seen halos before but the rings are uncommon and unexpected, and not quite understand by many. Sky-filling auroras, rainbows and lunar halos are each atypical sky phenomena that delight, and maybe make us tingle with anxiety a little.<br /><br />

<td>Berzelius? Is it true that this is a crater never featured on LPOD? Seems to be so, although it was mentioned at least [http://www2.lpod.org/wiki/August_31,_2013 once]. The lack of attention is understandable for it is a relatively shallow feature with a pretty flat floor. But in new LPOD contributor Adam's image above - excerpted from a mosaic of the entire waxing phase - I noted that the floor has a low ridge near the western rim, and there is a faint scratch on the floor. Intrigued by the scratch I looked at the LRO Quickmap (with its new design and features) and found a rille-like feature on Berzelius' floor. But also just to the top of the crater rim there is a small crater chain with about the same alignment as the scratch. The chain may be secondaries from Atlas, about 300 km to the north, but the scratch doesn't look like a crater chain. Linear rilles usually for in an extensive or volcanic environment, but this doesn't seem like either.<br /><br />

<td>There are two major observing targets here - Janssen and the Rheita Valley - and yet I am drawn to small features between them. Notice the alignment of the bottom end of the Valley and then look to the left for more linear features oriented in the same direction. The excerpt at left from Avani's image highlights five other small crater chains aligned in the same direction as the end of the Rheita Valley. All of these crater chains are from the formation of the Nectaris Basin. A real question is why are the Rheita Valley and the Snellius Valley so much larger than the other chains from this basin? Another question might be why does the far side of the Orientale Basin have so many large crater chains and the nearside has very few. Finally, did Imbrium also create large basin chains, and if so, why aren't they very visible, since Imbrium formed more recently than Nectaris?<br /><br />

Southeast of [https://the-moon.us/wiki/Dembowski Dembowski] (diameter: 26 km, depth: 1 km) and west of [https://the-moon.us/wiki/Godin Godin] (diameter: 34 km, depth: 3.4 km ) is a strange, rare, salient and understudied formation, characterized as a prominent plateau that rises above the surrounding surface. The formation is approximately 25 km X 20 km in maximum dimensions at its base. The highest point of this unusual formation reaches about 2.3 Km in relation to the lower region of the surrounding surface. On the upper face of the this interesting plateau is a wide, flat, horizontal and relatively smooth area, like a big table. This horizontal surface is at an altitude of approximately 1.5 Km compared to the lower surface of the surrounding region, and has approximately an area of 50 Km2, or substantially the same area occupied by a crater with 8 km in diameter. This detached flat surface hosts inside a tiny crater about 2 km in diameter. Another small crater 3 km in diameter is positioned on its southern edge.<br /><br />

For a long time now I've failed in acquiring any new lunar images, mainly due to the fog, clouds or low temperatures. So I've decided to look back in time at some images, and try to reprocess them. <br /><br />
<br /><br />
This is how I found the following images, depicting the abrupt color boundary between Mare Serenitatis and Mare Tranquillitatis. They also show the region around Lamont, with it's ghostly spots around it, part of which are present in the Apollo 11 landing area. Also 8 or more domes are just visible near Rupes Cauchy. The entire image, despite it's low to moderate resolution, is filled with rimas or faults. <br /><br />

This is a favorite area of the Moon for me. One reason is that it is conveniently (except on cold winter nights) visible early in the evening. And the second reason is that the scenery is fascinating. This is a region of small bright craters and broader dark lava fills. The biggest maria are Marginis, Smythii, and the eastern edge of Crisium. Many of the smaller dark patches fill crater floors and other low spots in the moat between Crisium Basin rings. But also from here south towards Australe the land seems like it was swampy, with lava rising to the surface where ever it could. And look at the limb beyond Neper - is that plateau a profile view of a crater rim? Finally, what rarely seen Lunar 100 object is visible here?<br /><br />

Although topographic profiles from LRO QuickMap reveal things previously unknown to me, I find it more pleasing to learn new things from telescopic viewing or imaging. Gary's sunrise view across Posidonius and Le Monnier provides plenty of surprises. The shadows reveal the floor of Posidonius to be more exotic than it normally seems. It is very impressive that shadows make the meandering rille crossing the western part of the floor easily visible, even though it may be below the resolution limit of the image. Also remarkable is the depiction of a shadow-casting ridge just west (to the left) of the rille. This is not hinted at in excellent [http://www.lpod.org/archive/LPOD-2004-09-15.htm images] under high illumination, but Jim Phillips' classic [http://www.lpod.org/archive/LPOD-2005-05-02.htm image] does show that the floor bends downward, but west of where this shadow starts. An LRO topo traverse does reveal that there is a 130 m vertical drop off in 6 km of horizontal distance. Gary's image captures a significant topographic feature that is totally invisible in any other imagery I've seen, but caused me to use LRO topography to investigate a part of the crater floor that perhaps never otherwise would have been looked at. Finally, the odd shadow across the floor of Le Monnier is also unexpected, for none of the rim looks irregular enough to cast such a mountain of a shadow. Isn't <em>shadow magnification</em> wonderful!<br /><br />

Seems that this February 1st, the Moon was almost Full and the calendar was wrong…or maybe not? Actually it was right, in this smile view of the Moon captured from Almada, Portugal, I could see the night side of the Moon very well illuminated by the Earth reflected light, like if it was Full Moon. This impressive phenomenon, known as Earthshine, was described and drawn for the first time, by the great Leonardo Da Vinci about 500 years ago on his book <em>Codex Leicester</em>. Leonardo da Vinci explained the phenomenon in the early 16th century when he realized that both Earth and the Moon reflect sunlight at the same time. Light is reflected from the Earth to the Moon and back to the Earth as Earthshine.<br /><br />

Last September my wife and I went to White Sands National Monument in New Mexico to attend their monthly &quot;Full Moon Hike&quot;. The sun was setting in the west and generating crepuscular rays that went across the entire sky. They converged as anti-crepuscular rays in the east, around the rising full moon. The shape of the cloud is certainly evocative of other events that occurred in the New Mexican desert. But this cloud was less explosive, being a &quot;Cumulo Nimbus&quot; formation that was pretty distant from our location. It's basically a thunderhead storm cloud with perhaps a downpour at the bottom of the column.<br /><br />

Yesterday's [http://www2.lpod.org/wiki/February_5,_2014 LPOD] discussed the smooth deposits just beyond the northern rim of Theophilus. Those materials are impact melt ejected during the end stages of formation of the crater. The melt fell out of the sky and flowed downhill and collected into ponds. Their smooth surfaces show that the melt was fluid and able to settle into relatively flat surfaces. A second set of flat surfaces was made by the mare lavas at top center (Mare Nectaris) and bottom right (Sinus Asperitatis). A third smooth surface is very conspicuous to the left of <span style="line-height: 1.5;">Capella. Remember that Capella is the crater with the central peak and sagged interior walls, and Isidorus is the nearby flat-floored crater with a fresher crater on its floor. Capella also has a slightly ambiguous stratigraphic relationship with the Capella Valley, a short secondary crater chain emanating from the Imbrium Basin. The smooth surface east of Capella has a shape roughly like the state of Illinois, and is bounded on the left by a ridge. This surface is remarkably smoother and younger looking than nearby terrain with the Gutenberg Rilles. It is unlikely to be impact melt because there is no young crater large enough and near enough to be a likely source. Presumably it is relatively young mare material, but it is not dark under high Sun [http://www.lpi.usra.edu/resources/cla/info/eii/ lighting]. So perhaps it is older mare veneered with bright ejecta from Theophilus. In fact, if you look at the LRO [http://bit.ly/1nbUbbn QuickMap] the Illinois patch is cratered, sparsely, and mainly differs from nearby terrain in not being rough textured. The roughness may be due to rubbly debris from the formation of a basin. Imbrium is further away, but this area is inside the Altai Ring of the Nectaris Basin, and Nectaris ejecta would not be expected inside that ring. So, Illinois is, perhaps, an isolated patch of lava that escaped to the surface in a region littered with Imbrium debris.</span><br /><br />

<br /><br />
This stunning image comes from an Italian amateur I had never heard of - but I hope to see much more from in the future. Riccardo uses a normal 8″ Celestron and somehow gets these extraordinary results. At upper right is Theophilus and seen very clearly are smooth ponds of impact melt just beyond the rough rim mound of debris - called a glacis in 18th century Moon books. These are not volcanic rocks, which by definition are melted by heat from within the world, but are impact melts that were melted by the tremendous energy of the impact that created Theophilus. The melt rocks originated inside the forming crater and were ejected near the end of the process, as seen by the fact that they drape the uplifted and fallback-created rim. Beyond the melts is a continuous layer of ejecta that gives way to regions intensely pitted by secondary craters. Theophilus is a young enough crater (not dated but probably between 1 and 2 billion years old) that much of its original ejecta deposits are still visible. Now just imagine that every crater on the Moon was originally surrounded by impact melt that extended about once crater radius beyond it’s rim, and continuous ejecta out about one diameter, and scattered secondaries for tens of crater diameters, and rays perhaps for hundreds of crater diameters. You can see that the surface layers of the Moon are a mixture, with a lot of material from nearby craters, and some from craters quite far away. So a soil sample collected anywhere on the Moon includes material from many different cratering events.<br /><br />

Somehow I missed this when it came out, presumably around Christmas time. It is an excellent short video which recreates moment by moment the accidental imaging of Earthrise 45 years ago by the Apollo 8 crew. The reconstruction by the Goddard Scientific Visualization Lab was only possible because of the Lunar Reconnaissance imaging and topographic mapping. I can see that accurate recreations are possible for every significant lunar exploration - and planned future ones. <br /><br />

<br /><br />
We see the Moon with eyes that are most sensitive to the visible range of the spectrum, and our digital cameras are similar, but extend more towards the near infra-red. Other sensors observe in other wavelengths and see different things than we do. An [http://www.hou.usra.edu/meetings/lpsc2014/pdf/2069.pdf abstract] for the upcoming 45th Lunar and Planetary Science Conference provides an example when looking at the [https://the-moon.us/wiki/Rima_Birt Birt Rille]. Start with the LRO image at right, which is similar to telescopic [http://www2.lpod.org/wiki/August_20,_2009 views]. The mare surface is cut by the rille, which has an elongated deep vent near the center of the image. The high Sun illumination hides the dome that the vent bisects, but it is visible on appropriate telescopic [https://the-moon.us/wiki/LPOD_Feb_17%2C_2008 images.]. The purple colored image, from the Diviner instrument on the LRO spacecraft, maps regolith temperature. The purple areas have a temperature of 2 K, and the red areas are 30 K.The green, yellow and red areas are hotter than the mare because their sloping walls (of small craters and the rille) expose small rocks and boulders that hold heat longer than the mare. The white arrows indicate the limits of a pinker purple area - this is a thin layer of pyroclastic ash that is free of rocks and is thus cool. The middle image is made from radar data from the Mini-RF on LRO. CPR is circular polarization ratio, a measurement that highlights the occurrence of rocks in the upper tens of centimeters of regolith. The dark area around the rille, marked by the arrows, maps the limit of the pyroclastics to a greater extent than revealed by the Diviner thermal infra-red imaging. This suggests that the pyroclastics erupted not just from the vent but also from the rille itself - perhaps the small pits along the rille were also vents. It is remarkable that this same boundary seen in the radar is visible in an amateur's low Sun [https://the-moon.us/wiki/LPOD_Feb_17%2C_2008 image] - take a careful look.<br /><br />

<br /><br />
The [https://the-moon.us/wiki/Rupes_Altai Altai Scarp] is one of the most dramatic basin rings on the Moon, casting long shadows in the lunar afternoon. But as Julio's image shows, the scarp is not continuous, taking an abrupt dip along its southwest edge. Two long shadows bracket a place where the scarp basically disappears. The broad flat plain to the left of the gap is the floor of an old battered crater, Rothman G. Did G form before or after the scarp? If afterward, that could account for the lowering of the scarp wall - the expanding shockwave from the crater-forming impact destroyed the basin rim. But the debris of the collapsed scarp isn't visible to the right. This area is covered by lava flows that perhaps covered the debris. If the crater formed first, the subsequent formation of the scarp would have cut right through a low spot - the crater rim and floor, so that the scarp would be lower than expected. This seems like a more reasonable explanation, but it is really arm-waving. That is what it is called when interpretation gets ahead of facts.<br /><br />

When Apollo spacecraft were orbiting the Moon, a crew member in one would often [http://apod.nasa.gov/apod/ap090719.html photograph] the other vehicle, but I am not aware of any other imaging of one robotic spacecraft by another. (For the Moon that is; dramatic [http://en.wikipedia.org/wiki/File:MRO_sees_Curiosity_landing.jpg imaging] of vehicles near Mars has occurred.) The LRO camera team worked with the LRO navigation team and the LADEE operations folks to determine when LRO could image LADEE. On Jan 15, LRO passed 9 km above and to the side of LADEE and the picture was taken. But the planning had to be precise because LADEE is in an equatorial orbit and LRO follows a polar path, and each is moving really fast (about 3500 miles/hr). Mark Robinson, PI of LROC, explains the details of how they did it, and then reduces the smear in the rapidly moving LADEE blur to recreate an image of the 1 by 2 m spacecraft that has, arguably, identifiable spacecraft parts.

A couple of years ago, Maurice Collins very generously shared an image that he created using LRO data. He took the LRO nearside mosaic and combined it with the LRO shaded relief topographical data, then added hundreds of labels, creating an amazing map of the moon. I knew as soon as I saw that I would eventually put it to work at the telescope. Well, I finally got around to putting something together. I gave the file to a friend in the graphics business and he printed the image on adhesive-backed vinyl. I let him choose the size that he thought would work best and it wound up being 21" x 21". From there I’ve constructed a lightbox that illuminates the image from behind. I’m very happy with the final outcome. It’s a joy to use at the telescope and I can’t wait to bring it to an outreach, where I’m sure the guests will be just as thrilled. The image depicts the 8 steps involved in constructing the Moon map lightbox.<br /><br />

This is a beautiful image. Despite the dramatic lighting that picks out every change of slope of the Jura Mountains crater rim, I am immediately attracted to the line of secondary<br />
craters that heads towards the crater Bianchini that is mostly enshadowed on the Jura rim. This line appears as a diffuse ray under high Sun [http://www.lpi.usra.edu/resources/cla/images/lores/y842.jpg illumination], probably originating at <br />
Copernicus. In Damian's image the individual secondary craters are clearly visible. Also obvious, in an understated way, is an impact crater nearly completely submerged by a lava<br />
flow. It occurs near the center of the Sinus Iridum lavas and usually it is undetectable but with this low lighting it casts a shadow. LRO QuickMap shows it to be about 5 km wide and<br />
80-100 m deep. Part of the northern and western rim rises about 10 m above the mare surface. If you follow the ray up to the Jura rim you will find a similar ghost crater, a little<br />
smaller and shallower. These two craters are similar to a smaller [http://www2.lpod.org/wiki/August_19,_2012 one] previously detected near Helicon. Ghost craters demonstrate that mare lavas were not erupted all at one as one<br />
thick layer. Many individual lava layers were erupted and there was time between them for impact craters to form and often be buried by subsequent layers. Finally, sticking with the<br />
subtle features, notice the dome-like swell near Jura's eastern rim. The Geologic Lunar Research group has studied this feature, but the shading suggests that it may extend further to<br />
the north than I realized.<br />

We only have one? Here is a region with many interesting formations including the hills north of Apennines as well as the southern Caucasus Mountains, Mons Hadley, and even Promontorium Fresnel, and the Fresnel Rimae are easily visible. But what really interests us in this photo? What matters for us Brazilians is a small crater to the left of the Fresnel Promontorium with the suggestive name &quot;[https://the-moon.us/wiki/Santos-Dumont Santos Dumont]&quot;! This crater, just 8 km in diameter, is the only on the Moon named for a fellow Brazilian, an aeronautical engineer who lived from 1873 to 1932. <br /><br />
Until recently, no more than 10 or 15 years ago, to make a photo of Santos Dumont in Brazil was unthinkable for a simple amateur astrophotographer. This required large aperture instruments only accessible to professional observatories, so that the first Brazilian to achieve a clear photograph of Santos-Dumont was our colleague Nelson Travnik using the great German bezel, single CA Steinheil in the country, belonging to the Centre Astronomical Piracicaba, this just in on September 20, 1996. Since then, fortunately, much has changed! Telescopes have become more accessible, affordable and with improved optics. With the technique of CCD and CMOS photo then the jump in quality was fantastic. Currently any amateur with reasonable resources can get an image of Brazil's named crater! <br /><br />

Every day a few thousand people from around the world visit LPOD. Each year, hundreds of these visitors submit images and comments. Even though most of us never meet and mostly don't exchange emails, LPOD is the center of a community of observers brought together by a mutual love of the Moon. Recently, one of the LPOD community has died. Cordula Bachmann writes that her friend Wilfried Tost, who was <em>a member of DLR group, LPOD member since August 2010, and highly esteemed, honoured and respected supervisor of the Berliner Mondbeobachter (Moon Observers), passed away Jan. 12th, aged 61. He has left a gap that can never be filled. His last email to me was about LPOD. On Nov. 14th he wrote me that you [CAW] already answered my comment about Miyamory Valley of Nov. 12th. The next day he was too ill to write. I printed and read every LPOD to him in hospital until about Christmas.</em> I am touched that both Wilfried and Cordula found LPOD worth talking about at a critical time of life. Wilfried contributed an [http://www2.lpod.org/wiki/June_22,_2009 LPOD], published more than 40 articles about the Moon, digitized and ultimately placed [http://www.planetarium-berlin.de/Mondatlas/Nav/B006_0600.html online] the [http://www.planetarium-berlin.de/Mondatlas/info/Mondatlas_Buch.jpg Berliner Mond-Atlas], and as a member of the Institute of Planetary Research at the German Aerospace Center (DLR) prepared many weekly highlights of astronomy such as the one shown here. Wilfried already had an asteroid named for him (13,334 Tost), but the greatest compliment comes from his friends, as Cordula writes: <em>Our group, the Berliner Mondbeobachter at the Wilhelm-Foerster-Sternwarte, will never ever be the same without him. We miss his guidance and profound knowledge, but most of all his encouragement, his friendship and his kindness.</em><br /><br />

Sat on by Purbach at the top, and squeezed by Deslandres to the southwest, Regiomontanus is an older version of Copernicus. At 110 km in diameter it probably formed as a complex crater with a broad flat floor ringed by dramatic terraces, and a cluster of peaks near its center. A flat floor remains, but it is 3 km below its highest remaining rim, much less than its original 4-5 km depth, so it has been filled with a 1-2 km thickness of material slid down from it rims (talus it is called), and more importantly, with ejecta from the formation of nearby craters and basins. The left side of the floor holds one or more breached craters, showing that there was an interval of time between the formation of those craters and when their rims were cut through. The rille-like chain near the central peak and many others of the small craters on the floor appear to be secondaries, but surprisingly none are radial to <span style="line-height: 1.5;">Werner, which is nearby and youthful. The main reason anyone ever observes or talks about Regio is because its central peak seems to have a crater near its summit. Patrick Moore and others claimed that this was too unlikely to be an impact crater so the peak must be a volcano and the pit is its volcanic vent.And if the peak is volcanic probably the crater is too, and all the other craters as well. Forty to fifty years ago people looked for other possible pitted </span>volcanic<span style="line-height: 1.5;"> peaks and calculated the aggregate area of the peaks and the statistical </span>likelihood<span style="line-height: 1.5;"> that the pits were or were not </span>random<span style="line-height: 1.5;"> impacts. But the reality of the summit pits of many of the other examples, such as Plinius, were quite uncertain, and the argument proved nothing. Now we have multispectral images that show that the Regiomontanus peak and pit look just like the surrounding highlands rocks, with no evidence of a volcanic composition. Also, at high Sun the summit pit looks like a standard small impact crater. This is all consistent with the modern understanding of how central peaks form as the rebound of rocks from depth. Not a volcanic peak. Not a volcanic crater. </span><br /><br />

This morning I went out to watch the Moon set behind the mountains. It was a beautiful cold winter morning and the Sun was just about to rise. It was a bit cloudy down by the horizon, so this shot was the last one where the Moon was clearly visible, later it vanished into the distant clouds.<br /><br />

The [https://the-moon.us/wiki/Apollo_16_Site Apollo 16 landing site] (small, white cross) was selected so that astronauts could collect samples from two units expected to be volcanic. First was the relatively smooth material just to the left of the cross. Similar, non-dark (and hence not maria lavas) material is common in the lunar highlands - in fact, it fills [https://the-moon.us/wiki/Abulfeda Abulfeda] (large crater at bottom center) and other low spots nearby. This material is called [https://the-moon.us/wiki/Cayley_Formation Cayley Plains] (it was first recognized near the crater [https://the-moon.us/wiki/Cayley Cayley]) and was thought to be an older volcanic rock, perhaps not basalt but something with more silica. The more heavily textured, hilly or wormy material inside the crater [https://the-moon.us/wiki/Descartes Descartes] and extending to the north is called Descartes Formation; it was interpreted as an even more silica-rich volcanic rock. But when the Apollo 16 spacecraft landed, astronaut John Young could tell by looking out the window that the Cayley landing site wasn't volcanic. In fact, the samples show it to be made of breccias, which are glued together fragments of prior rocks. And none of the rocks fragments were volcanic. The smooth Cayley Plains are probably ejecta from Imbrium and perhaps other basins that flowed to fill low places when it landed - the ejecta was fluizied so that it flowed like a liquid. This was perhaps the biggest scientific surprise of the entire Apollo project. Unfortunately only a small amount of sampling was done along a snout of the Descartes Formation material just below the bottom of the cross on the image. This elevated area is called Stone Mountain, but no massive rock formation was found, only more breccias. However, it is not certain if the Stone Mountain samples are actually pieces of the mountain, or if they are ejecta from the nearby South Ray crater that excavated Cayley Plains material. Certainly the Descartes Formation is unlike any other recognized ejecta deposits, and I believe that we still don't know what kind of rocks it is made of.<br /><br />
