 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.
