Hi all,

Find here the last image coming from Dec. 1 session featuring Tycho and
environs.

The high Sun angle putted on evidence a dark grey and opaque aureola at
the feet of the crater, can you see that? This is less prominent on the
southern side according to the ejecta direction.
I never noticed this before, I guess it’s a debris accumulation.
