<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 />

<td><em>drawing by [mailto:erikarix1@gmail.com Erika Rix], Texas, USA</em><br /><br />
<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 />

<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 />
