After watching the satellite streak across the skies, I went back to view one of my favourite asterisms. All 10 stars of the Coathanger were easily seen - 6 of the hanger and 4 of the hook.

Identified the quite bright Aristarchus with its central peak in Oceanus Procellarum. Also noted the adjacent and much darker Herodotus. They appeared to be on a dark plateau and there was an even darker mountain range. I then slewed to the crater Plato which was easy to identify because of its roundness, white well-lit rim and the large dark-floor on the north shore of Mare Imbrium. I then slewed to Mare Crisium and discovered this small, bright white circular crater - Proclus. You could also see the well-lit rime on the NE edge of Palus Somni.
