Just as the last of the twilight fades by 7:15 this evening, you’ll find the nearly Full Moon again rising, to spend the night crossing the heavens. About an hour later, well to the lower left of the Moon, a marked bright object rises, much brighter than any star, the enormous Jupiter. The Moon slides even closer to Jupiter to open up October tomorrow.
October opens with a waning Gibbous Moon climbing into the east-northeast, followed quickly by the giant planet Jupiter at 8 o’clock. They’ll climb to due east, more than one quarter of the way up at 10 o’clock. The Moon’s orbit brings it around to another meeting with Jupiter on the 28th, the Moon shining as the Full Hunter’s Moon.
Autumn has not discouraged the Summer Triangle, just given us a different view. Seen crossing overhead near midnight in the summer, it now appears overhead in the evening. Look for the faintest of the three stars, Deneb, close to the zenith this evening, while Altair shines in the southwest, and the bluish-white Vega gleams sharply, high in the west.
