September's full moon of 2025 will also be a very special blood moon set to rise on Sept. 7 -- amid a total lunar eclipse and rare moment of totality.
Here are some quick facts about the lunar eclipse and what makes this September's full corn moon so special to watch.
This year's second total lunar eclipse will occur on Sept. 7, 2025 between 11:28 am and 4:55 p.m. Eastern but will not be visible from the United States this time around, according to Space.com. It will be fully immersed in the Earth's dark inner shadow for 82 minutes of totality between 1:30 and 2:52 p.m. Eastern.
Totality will be visible in parts of Australia, India, Cairo and South Africa. Approximately 77% of the world's population will be able to see totality and almost 88% seeing at least some of it. However it will not be visible at all from North America.
The next total lunar eclipse visible in the U.S. will be on March 2-3, 2026.
A lunar eclipse is an astronomical event that happens when the sun, Earth and moon all align so that the moon passes into the Earth's shadow, causing the moon to be darkened.
Unlike solar eclipses, totality can last up to nearly two hours and is safe to view without any eye protection.
The September corn moon of 2025 will be the next full moon, rising on Sunday, Sept. 7th and reaching peak illumination at 2:09 p.m. Eastern. It will appear full on both Saturday and Sunday evenings.
September's corn moon came to be called that because it corresponds with the time of year in late summer-early fall that harvesting corn takes place in the northern United States, according to Old Farmer's Almanac.
This year's corn moon will also be a blood moon.
The blood moon is a trick of the light, when the typical whitish looking moon becomes red or ruddy brown. It can happen during a total lunar eclipse, when the moon is fully in Earth's shadow and a little bit of light from Earth's sunrises and sunsets falls on the surface of moon, making it appear red.
A blood moon also describes a moon that appears reddish because of dust, smoke or haze in the sky, according to SpacePlace, or it can refer to one of the full moons of fall when the leaves are turning red.
The first day of fall, also known as the autumnal equinox, September equinox or the fall equinox arrives on Monday, Sept. 22 at 2:19 p.m. Eastern.
The October full moon, also known as the hunter's moon will occur on Oct. 6.
