Crescent Moon
           
10–11 November 2010
In autumn, the crescent Moon is low in the sky, and is only visible for a short while after sunset. But if you do manage to spot it, here are some things to look for. Often, it's not the largest lunar features that are the easiest to see. For example, to the west of the Mare Crisium is a small but prominent ray crater, Proclus (3), two of whose rays define a diamond shape called the Palus Somnii (4). Proclus is a small crater, 29 km across, but it's easy to spot because of its rays and location.

The three craters of Theophilus (5), Cyrillus (6) and Catharina (7) are also easy to spot. Near them is a ridge called the Altai Scarp (8). Other craters are:

1 Hercules
2
Atlas
9 Piccolomini
10 Janssen
11 Fracastorius
