On Friday, July 23, the moon will reach its full phase. On that evening, the libration of the moon will cause the moon to appear to tilt downwards and twist to the left a bit, allowing Earthlings to see features along the moon’s northeastern limb that are normally not visible (green labels). Major lunar features…

This simulated view of Sinus Iridum, the Bay of Rainbows, and the Golden Handle that envelops its western perimeter, was made using Starry Night software. Every month, a few days before full moon, the handle effect is visible with sharp, unaided eyes, and very easily through binoculars and backyard telescopes. The latter might also reveal…
