I took a quick break midway through an all-nighter to grab a quick set of images of the waning gibbous moon. Observing the moon in the morning sky is always interesting as we get to see details along the sunset terminator that we don’t see in the evening sky when the moon is showing its sunrise terminator. When the moon is in its waning gibbous phase you can see how the Altai Scarp is part of a range of mountains that form the outer ring of the Mare Nectaris impact basin. When the sun angle is just right you can follow the entire ring all around this circular flood plain. (Photo Credit: John Graham, 11/2/2023)
