Rupes Recta the Straight Wall (evening)

On Friday night, March 7, the pole-to-pole terminator that divides the lit and
dark hemispheres of the waxing gibbous moon, will fall just to the left (or
lunar west) of Rupes Recta, also known as the Straight Wall, a feature that is
very obvious in good binoculars and backyard telescopes. The rupes, Latin for
"cliff", is a north-south aligned fault scarp that extends for 65 miles (110
km) across the southeastern part of Mare Nubium, which sits in the lower third
of the moon's Earth-facing hemisphere. The feature is always prominent a day
after first quarter and day before last quarter. For reference, the very
bright crater Tycho sits due south of the Straight Wall.
