Posidonius A (11 km.) , the highest of the small central peaks and the tilted and uplifted concentric ridge were the last features catching the light at sunset inside the rim. Also visible and included in this sketch was the northern most portion of Serpentine Ridge. As temperatures were falling throughout the night, I found myself stopping to warm my hands indoors not once but several times. The lunar viewing was excellent this night. Sketching: For this sketch I used: black Strathmore 400 Artagain paper, white and black Conte’ pastel pencils and a blending stump.

Like how you sketched the ridges. Makes me want to go out and sketch the Moon, but weather was very bad last months in Belgium. 10°C and rain... that ain't no winter!

I don't like to sketch when the temperature falls below about -7 degrees C. It justs gets too uncomfortable quickly. If I had know in advance what the air temperature was I would not have started this sketch. -- Eric, it was a great night to observe but I should have kept my gloves on. -- Tom, Tonight, Sunday night, was the best night with very steady air. Jupiter was awesome. -- Michel, On the night I sketched Posidonius I got a pretty good look at comet C/2012 K5 but my skies are not the best to the north east with Chicago nearby.
