Moon Phases

Tuesday, September 2, 7:11 a.m. EDT

First Quarter Moon

The First Quarter Moon rises around 2:30 p.m. and sets around 12:30 a.m. It dominates the evening sky.

Monday, September 8, 9:38 p.m. EDT

Full Moon

The Full Moon of September is known as the Harvest Moon because it is the Full Moon closest to the autumn equinox on September 22; it is also sometimes known as the Full Corn Moon. It rises around sunset and sets around sunrise; this is the only night in the month when the Moon is in the sky all night long. The rest of the month, the Moon spends at least some time in the daytime sky.

Last Quarter Moon

The Last Quarter Moon rises around midnight and sets around 3 p.m. It is most easily seen just after sunrise in the southern sky.

New Moon

The Moon is not visible on the date of New Moon because it is too close to the Sun, but can be seen low in the East as a narrow crescent a morning or two before, just before sunrise. It is visible low in the West an evening or two after New Moon.
