  • The 2020 full Corn Moon will reach maximum brightness on Wednesday, September 2.

  • This will be the last full moon before the autumnal equinox.

  • September only takes the name Corn Moon when it’s not the annual Harvest Moon.

Just like that, another month is behind us and it’s time to view another full moon. The last one before the autumnal equinox, the full Corn Moon will rise in the early morning on September 2, according to NASA.

When is September’s Corn Moon in 2020?

NASA and Farmers’ Almanac report that the Corn Moon will reach maximum brightness at 1:22 a.m. EDT on Wednesday, September 2. And if you’re usually early to sleep, no worries. You’ll be able to watch the moon rise after sunset on the evening of September 1.

The sunset timing will depend on your exact location, but on the East Coast, it will lower below the horizon at approximately 8:07 p.m. EDT on Tuesday. To figure out when the sun will fall where you live and plan accordingly, you can use The Old Farmer’s Almanac sunrise and sunset calculator.

Wait, it’s not a Harvest Moon?

This is where it gets kind of tricky. According to The Old Farmer’s Almanac, September only takes the name Corn Moon when it’s not the annual Harvest Moon, which is the full moon that falls closest to the autumnal equinox. Typically, because the equinox occurs on September 22 or 23, September takes the Harvest Moon moniker. But this year, because the full moon falls early in the month, that’s not the case, and October will host the Harvest Moon.

Although it’s not always used annually, the name Corn Moon is pretty self-explanatory. It represents the best time for harvesting the crop.

So, when’s the next full moon?

Get excited, October is running a two-for-one special this year! That’s right, there will be two bright lunar shows to attend within the month—one at the beginning, and one at the end. The first Harvest Moon will rise on October 1, per NASA, and will reach full opacity at 5:05 p.m. EDT, to be enjoyed through the evening and into night.

On October 31, another full Blue Moon will peak, just in time to honor Halloween. Farmers’ Almanac and NASA report it will shine brightest at 10:49 a.m. EDT. When it’s not the second of two monthly full moons, it’s known as Hunter’s Moon.
