Full Corn Moon

September’s full Moon reaches its moment of fullness at 11:49 a.m.

Quoth Farmers’ Almanac: “While September’s full Moon is usually known as the Harvest Moon, if October’s full Moon happens to occur closer to the equinox than September’s, it takes on the name ‘Harvest Moon’ instead. In this case, September’s full Moon is referred to as the Corn Moon.”

Every three years the Harvest Moon falls in October, so not every full Corn Moon is a Harvest Moon.
