Notes

Sketched with white and black charcoal on black paper at the eyepiece over 30 mins between 20h and 21h UT, so the sketch was in fact started before the fall of darkness. Archimedes lies exactly on the illuminated side of the terminator.

Also visible are craters Autolycus and Aristillus as well as the Apennine and Alp mountains (with the beginning of the Alpine Valley) and the solitary Mt Piton.
