Often, the September Moon is also called the Harvest Moon, but this year the Harvest Moon occurs in October. The Harvest Moon is the Moon that falls nearest the autumnal equinox; this full Moon provides the most light at the time when it’s needed most—to complete the harvest!
Technically speaking, however, the moonrise for the September 2017 and October 2017 full Moons are very close this year. For several days after both full Moons, the Moon rises a shorter-than-usual time after sunset, creating more light during harvest time. During both months, the Moon will hang large after sunset, casting its beautiful light on our fields of grain.
