September’s ‘Corn Moon’ rises this week

Our next full moon, and the final one of the astronomical summer, is set to rise above the horizon this week on Sunday, September 7th.

This full moon is called the Corn Moon as opposed to the Harvest Moon which traditionally is the full moon that falls closest to the autumnal equinox (September 22nd). It just so happens that the next full moon will occur on October 6th so it gets the name Harvest Moon this year.

The moon will officially be full at 2:09 pm EDT Sunday, so it won’t be seen until hours later when it rises above the horizon after sunset.

This year’s Corn Moon will actually coincide with a lunar eclipse for much of the Northern Hemisphere (Europe, Africa, and Australia), but no eclipse will be visible across the U.S. Other countries can expect a long-lasting “blood moon” similar to what America saw back in March earlier this year.

The name of the moon is a reference to the corn harvest, which typically happens this time of the year across North America.

The best viewing will be after sunset on Sunday.  To find the best time to view in your area, check out the moonrise calculator. Be sure to find a place with unobstructed horizon views for the best sights.

The next full moon will be the Harvest Moon, which occurs on October 6, 2025. As mentioned earlier, the Harvest Moon is whatever full moon falls closest to the Fall Equinox. Usually that is in September, but every four or five years, it happens in October.
