Craters in the southern part of the Moon thrown in to relief by the 92% illumination on 20240420. The most prominent upper right is Tycho. Its terraced outer walls rise 4,800m above the floor. Below it, the largest is Clavius, with a diameter of 245km. The elliptical crater lower left is Schiller, which perhaps was two overlapping craters but might possibly have been carved by a very low angle impact. The very large crater just emerging from shadow, upper left, is Schickard. In this light its floor appears to be convex.
