A New Crater?

MoonCopernicus070707LPOD.jpg
image by Bob Pilz

As soon as I saw Bob’s photo I thought, Wow! That is a very bright crater pit on the west edge of Copernicus that I don’t remember seeing before - is it new? A quick search of the LPOD Photo Gallery did not reveal the crater. Excitement mounts. So then I searched the world’s best collection of high resolution lunar images - LPOD - and found the crater grinning at me on Wes Higgins’ great Mars, giving us further reason to appreciate the shielding properties of Earth’s atmosphere!

Chuck Wood

PS: Bob has detected 8 crater pits of his image within the floor of Copernicus, the smallest about 750 in diameter - we can almost detect new craters with amateur telescopes!
