 Here we see the battered southernmost limb of the moon, at just over half waxing phase. The large crater on the terminator just emerging is the second largest crater on the moon, Clavius. Tycho is just above it with the obvious central peak. This is the source of the massive ray system covering the globe seen best during full moon.
