I've never seen some of these craters before. Yes, Gauss at far left has been [http://www.lpod.org/?m=20061226 imaged] occasionally, but [http://www.lpod.org/?m=20061227 dark-ray crossed Hahn] and even Plutarch are rarely imaged with good resolution. Now in this marvelous clip from a broader [http://objectstyle.org/astronominsk/Moon/Moon2009/Moon_20090531_2x_en.htm mosaic], Yuri, Mikhail and Konstantin have revealed all these craters and others closer to the limb. The star is [https://the-moon.us/wiki/Joliot Joliot], a 164 km diameter, mare-floored with a rubbled central area that looks like it was trying to form a ring. Seneca is marked with a question mark, not because I am uncertain of the identification, but I am quite doubtful that that name is warranted. <br />
