The Full Harvest Moon this evening 8.30 pm

Harvest moons are full moons that occur every year closest to the autumnal equinox, or beginning of fall, usually Sept. 22 or 23.
This year's harvest moon arrives Sept. 20 and will appear exactly opposite the sun at 7:54 p.m. EDT.

It’s called the harvest moon because the moon rises about the same time every evening for a few nights in a row in the Northern Hemisphere.
It provides ample moonlight in the early evening for farmers harvesting summer crops.

The phenomenon occurs because of the moon’s position in the northern part of the sky during this time of year. In the Northern Hemisphere, the farther north an object is from the equator, the longer it’s visible across the sky.
