Many people fail to notice the Moon in the daytime sky, but in fact it is frequently visible during the day, but has low contrast and doesn’t attract attention. LPOD has featured a number of previous daytime images, demonstrating that we have more opportunities for appreciating our pocked orb than even most lunar observers probably realize. Perhaps daytime study of the Moon can make astronomy a normal schooltime activity. And now Alan has taken an image with high resolution more typical of an excellent evening view - in fact, if you adjust the contrast you can darken the blue to a steely hue, as if it were a great evening view. Here it is in higher resolution, and if you click the link you can see the bright International Space Station streaking across this dark Moon.

Note: I missed LPOD yesterday, and in fact missed most of the day, for I spent 27 straight hours at my office completing a proposal to manage NASA’s national intern program. Seeing the Moon at any time of day is pretty hard from indoors.

    A very good point in that the moon visibilty in the day-time sky could be turned into a school-time activity. How few science teachers are even aware of its visibility during the day? I remember the first time I saw the moon during the daytime in 1965, as a kid on the school oval. I was stunned. However no-one else took the slightest interest. A view that astronomy can be a daytime activity (sunspots, meteor radar reflectance, the moon, spotting Venus) should be promoted.

  2. This is another lunar work of art, and it epitomizes the stunning beauty or our partner in space.

  3. I love looking at the Moon in a crisp blue sky through 7×50mm binoculars and todays image is a wonderfull site. Thanks for the image Alan.

  4. Great comment about using the daytime moon as a school astronomy activity. I’m going to pass that idea along to a friend at JPL who does public outreach. And I wish you good fortune on your proposal. Kay

  5. Chuck,

    Each month I print out a list of moon rising, transit and setting times, primarily to help me locate the Moon in the daytime sky. It’s a rewarding thing to find a rather thin crescent especially in a deep blue morning sky when the contrast is quite beautiful. The Rooks and Cordilleras, and the northwestern highlands, make such a lovely white “frame” on the western edge of Oceanus Procellarum and the maria. Our Moon is a great gift day and night. Alan Friedman’s image is strikingly beautiful. I’ll add it to my binder full of LPOD’s and your monthly Sky & Telescope articles.
