On Wednesday, September 2 the full moon, called the Corn Moon - will reach peak fullness at 1:22 a.m. EDT (5:22 UTC). The Moon will appear full for about three days, from Monday evening through Thursday morning. The Corn Moon occurs every 3 years.
In Europe, the Corn Moon is called the Fruit Moon, as fruits ripen around this time, and the Barley Moon, from the barley harvest.
Coming so early in the month, this sets the stage for two full moons in October. The second full moon - called the Harvest Moon - will shine on Oct. 31.
The Algonquin tribes called this the Corn Moon, as this was the time for gathering their main staple crops of corn, pumpkins, squash, beans, and wild rice.
