When to See the Full Moon in September
September’s Full Moon is at its most illuminated at 18:08 UTC on September 7, 2025.
The Moon always appears full in the days before and after peak illumination. Full Moon is the only phase where the Moon is up all night, with moonrise and moonset occurring around sunset and sunrise.

Blood Moon on September 7–8
This month hosts 2025’s second eclipse season, where we’re treated to two eclipses: a total lunar eclipse and a partial solar eclipse.
On September 7–8, Earth’s shadow will eclipse the Full Moon for the longest Blood Moon this year. Totality—where the Moon turns dark red—will last around 1 hour and 22 minutes. Anyone on the night side of Earth can see a lunar eclipse, and in this case, that is Australia, Asia, Africa, and Europe.

The second eclipse this season is on September 21/22. The Moon’s shadow hits the bottom of our globe, giving us a partial solar eclipse. New Zealand is in a prime position for this one, although the eclipse can be seen on various Pacific islands, in parts of Antarctica, and along a thin strip of Australia’s east coast.
You can see this eclipse in our live stream. This time, we’ve teamed up with Dunedin Astronomical Society in New Zealand to show the eclipse as the Sun rises on the morning of Monday, September 22—although the date of the eclipse is September 21 in UTC time. That is, weather permitting, of course. Clear skies!

Around September 8, the Moon meets up with Saturn. It will be possible to see the close approach between an almost Full Moon and the Ringed Planet all night, so look up and enjoy. See what it will look like in New York, USA, London, UK, and Sydney, Australia.
Around September 16, the Waning Crescent Moon meets up with Jupiter. Look up just before sunrise to find the pair in New York and London. In Sydney the pair will be closer on September 17, and will rise over the north-eastern horizon just before sunrise.
Around September 19, an almost New Moon aligns with Venus and the star Regulus. The trio will rise around sunrise, getting lost in the glare of the Sun in the early morning in New York and London. In Sydney, it may be challenging to spot Regulus as the Sun rises right after the trio appears over the eastern horizon.
Remember: Do not try to observe objects close to the Sun while any part of the Sun is above the horizon. Never point binoculars or a telescope in the direction of the Sun—it can cause permanent eye damage.
The Full Moon in September Is the Corn Moon
September’s Full Moon is known as the Corn Moon, Green Corn Moon, or Full Corn Moon, because Native American tribes harvested their corn around this time.
The Anglo-Saxon name is Harvest Moon, although our modern Harvest Moon will be in October as it is the Full Moon closest to the fall (autumn) equinox. Celtic and Old English names are Wine Moon, Song Moon, and Barley Moon.
