The Corn Moon of 2025 will be unlike any other in recent memory. On Sunday, Sept. 7, the September full moon will coincide with a total lunar eclipse. In a trifecta of skywatcher events, the Total Eclipse happens during a Full Corn Moon that is also a Blood Moon.

The moon will become a dramatic shade of red, which makes it one of the year’s most spectacular astronomical events.

When and Where to Watch the Corn Moon

The September Corn Moon will reach peak illumination at 2:09 p.m. Eastern on Sept. 7, according to the Old Farmer’s Almanac. While it will appear full on both Saturday and Sunday evenings, the eclipse itself will not be visible from North America.

Instead, totality will be best viewed across parts of Australia, India, Cairo, and South Africa.

According to Space.com, the eclipse will last nearly 82 minutes of totality, from 1:30 to 2:52 p.m. Eastern, with partial phases extending between 11:28 a.m. and 4:55 p.m. Eastern. In total, almost 88% of the world’s population will see at least part of the event, while 77% will witness totality.

What is the Corn Moon?

The Corn Moon is the name given to September’s full moon, tied to the harvest season in the Northern Hemisphere. The name originates from Native American traditions, when tribes marked the time for gathering corn and other crops. The Abenaki called it the “Corn Maker Moon”, while the Dakota referred to it as the “Corn Harvest Moon.”

“September’s full moon has always symbolized a turning point — from summer’s abundance to the preparations of autumn,” the Almanac notes.

Why This Moon Will Be a Blood Moon

This year’s Corn Moon is also a Blood Moon, occurring during a total lunar eclipse. When the Earth passes directly between the Sun and the Moon, sunlight filters through Earth’s atmosphere, scattering shorter blue wavelengths and leaving the longer red ones to cast a reddish glow across the lunar surface.

According to NASA’s SpacePlace, “the Moon looks red during a total lunar eclipse because of the way Earth’s atmosphere bends and scatters sunlight, bathing the Moon in the colors of all the world’s sunrises and sunsets.”

Looking Ahead
