South is up in this image, more info below.
With the moon 6 days past new, the shadows
fall steeply over a spectacular triplet of craters on the upper
right. These are from the bottom up Theophilus, Cyrillus, and
Catharina which is the oldest and most degraded in appearance.
Exactly in the center is an open ended small circular mare region
(sea) called Sinus Asperitatis, a highly disturbed area with
chains of secondary craters from the impact of Theophilus.
