The Moon is Full each month as it reaches a position exactly opposite the Sun, so tonight’s Full “Harvest” Moon rises as the Sun sets, and then sets as the Sun rises tomorrow morning. This timing can vary due to the Moon’s tilted orbit, about 5 degrees compared to the Earth’s orbit around the Sun.

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.
