The waxing Gibbous Moon continues to grow larger and brighter in the evening skies, overwhelming the fainter stars, and leaving us to view the brighter stars, including those of the Summer Triangle. As the Moon crests due south at 8:00 PM, you’ll find the lowest in this trio of stars, Altair, well above the Moon.

At 8 o’clock this evening, the Gibbous Moon, well right of Saturn in the southeast, may appear slightly rounded where day meets night on our celestial neighbor, a line called the “terminus”, where the sunlight terminates. The shadows are at their greatest near this line, revealing the larger craters in binoculars, or a spotting scope.

Late this afternoon, the waxing Gibbous Moon climbs into the east-southeast, still fairly low as the twilight fades, revealing a companion to the Moon, the planet Saturn. They’ll swing a bit higher into the southeast by 7:45, and then crest due south three hours later.
