Out On a Gaussian Limb
image by Yuri Goryachko, Mikhail Abgarian & Konstantin Morozov, Minsk, Belarus. North mostly to the left.
I've never seen some of these craters before. Yes, Gauss at far left has been imaged occasionally, but dark-ray crossed Hahn and even Plutarch are rarely imaged with good resolution. Now in this marvelous clip from a broader mosaic, Yuri, Mikhail and Konstantin have revealed all these craters and others closer to the limb. The star is 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.
