September 2025’s Full Corn Moon to Feature Dramatic Total Lunar Eclipse and Saturn Conjunction

A Celestial Spectacle Approaches

A total lunar eclipse of the September full Corn Moon will occur on September 7, 2025, visible across Antarctica, Australia, Asia, the western Pacific Ocean, the Indian Ocean, Europe, the eastern Atlantic Ocean and Africa.

The Full Corn Moon will reach its peak illumination in Pisces (15 degrees) on September 7, 2025, at 2:09 p.m. EST (11:09 a.m. PST).

Timing and Visibility

The eclipse will begin at 17:30 UTC when the moon starts passing through Earth’s umbra (darkest part of the shadow). Total eclipse will last from 17:30 UTC to 18:53 UTC, with the greatest eclipse occurring at 18:11 UTC. The moon will completely exit the umbral shadow by 19:56 UTC.

The duration of totality will be impressive, lasting almost an hour and 23 minutes: 83 minutes!

A Rare Astronomical Alignment

After sunset on September 7, the bright full moon will be positioned near Saturn and will remain visible throughout the night. During the total eclipse, when the moon’s glare is significantly reduced, both Saturn and the star Fomalhaut might become visible.

Cultural and Scientific Significance

This September full moon is known as the Corn Moon, a name derived from the traditional corn harvesting period. It holds special significance as the third and final full moon of the Northern Hemisphere summer, occurring between the June 21 solstice and September 22 equinox.

This spectacular event is part of a larger eclipse season, as it will be followed two weeks later by a partial solar eclipse on September 21, 2025. Eclipse seasons are approximately 35-day periods during which at least two eclipses must occur.

Looking Ahead

Astronomy enthusiasts should mark their calendars not only for this event but also for the coming months, as October, November, and December 2025 will feature three consecutive supermoons, making this an exceptional period for lunar observation.
