by Skywatchers are in for a treat this weekend as the Corn Moon, September’s full moon, lights up the night sky.
The Corn Moon will officially reach peak fullness at 2:10 p.m. EDT on Sunday, September 7, 2025, though it will appear brightest at moonrise and dusk later that evening.
Why It’s Called the Corn Moon
While many associate September’s full moon with the “Harvest Moon,” that title actually goes to the full moon closest to the autumn equinox. In 2025, that honor belongs to October’s full moon.
Instead, this month’s full moon is known as the Corn Moon, named for the late-summer harvest season across much of the northern United States. The name reflects long-standing agricultural traditions, and Native American cultures also referred to the August or September full moon with corn-related names, such as the Western Abenaki’s “Corn Maker Moon” and the Dakota’s “Corn Harvest Moon.”
A Rare Eclipse—But Not in North America
Coinciding with the Corn Moon, a total lunar eclipse will occur on September 7, creating what is often called a “Blood Moon.” Unfortunately, the eclipse will only be visible on the opposite side of the world, leaving North American viewers to enjoy the full moon’s brilliance without the eclipse.
Best Viewing Times
For the best view, look to the eastern horizon at dusk. Elevated areas and east-facing coastlines offer especially clear sightlines.
- New York City – Sunset: 7:20 p.m. EDT | Moonrise: 7:22 p.m. EDT
- Los Angeles – Sunset: 7:12 p.m. PDT | Moonrise: 7:19 p.m. PDT
The Corn Moon can be enjoyed with the naked eye, but binoculars or a small telescope will enhance the experience.
What’s Next?
After the Corn Moon, the next full moon will be the Hunter’s Moon on Monday, October 6, 2025. Traditionally marking the time for hunters to prepare for winter, the name dates back to at least 1710. October’s moon is also known as the Sanguine Moon or Blood Moon, a reference to both autumn colors and hunting traditions.
