Mare Humorum and Gassendi (all night)
On Thursday night, May 8, the terminator on the moon will fall just to the
west of Mare Humorum, the small, round dark patch in the moon's southwestern quadrant. Humorum is a basin formed during the moon's Nectarian Period approximately 3.9 million years ago. Views in a telescope on the nights before full moon will show arcuate wrinkle ridges near the eastern rim of the lava- flooded sector, the parallel curves of Rimae Hippalus outside the eastern border, and the prominent Rupes Liebig and Rimae Doppelmayer on the western rim. A darker region of the basin floor along the southwestern edge is
composed of volcanic glasses and ash deposits. On the basin's northern rim
lies the large floor fractured crater Gassendi.
