Moon, constellation, Saros
The moment of greatest eclipse takes place 2.7 days before the moon reaches perigee, its closest point from Earth for the month.
At mid-eclipse, the moon is located in the direction of the constellation Aquarius the Water Bearer.
The Saros catalog describes the periodicity of eclipses. This September 7 total lunar eclipse belongs to Saros 128. It is number 41 of 71 eclipses in the series. All eclipses in this series occur at the moon’s ascending node. The moon moves southward with respect to the node with each succeeding eclipse in the series.
The instant of greatest eclipse – when the axis of the moon’s shadow cone passes closest to Earth’s center – takes place at 18:11 UTC on September 7. The moon will lie at zenith – directly overhead – in the Indian Ocean. During the eclipse, the moon is located in the direction of the constellation Aquarius the Water Bearer.
Also, the duration of totality lasts almost an hour and 23 minutes: 83 minutes!
Next eclipse of this eclipse seasons
This total lunar eclipse of September 7, 2025, is followed two weeks later by a partial solar eclipse on September 21, 2025. These eclipses all take place during a single eclipse season.
An eclipse season is an approximate 35-day period during which it’s inevitable for at least two (and possibly three) eclipses to take place. In 2025 we had another eclipse season in March with a total lunar eclipse on March 13-14 and a partial solar eclipse on March 29.
September full moon is the Corn MoonAll the full moons have popular nicknames. Popular names for the September full moon are Harvest Moon, Crow Moon and Barley Moon. The 2025 September full moon is the Corn Moon. This name comes from the traditional time for harvesting corn.
The September 7, 2025, is the third and final full moon of our Northern Hemisphere summer (or Southern Hemisphere winter). That is, it’s the third of three full moons to fall between the June 21 solstice and September 22 equinox. Although it’s not the Harvest Moon, it’ll share some characteristics with that famously named moon. The Harvest Moon is the closest full moon to the autumn equinox. In 2025 it’ll fall overnight on October 6-7 for us in the Northern Hemisphere.

Some Harvest Moon characteristics
What is a Harvest Moon, and how will this September 7 full moon resemble the Harvest Moon, even though it doesn’t bear that name? The Harvest Moon – the closest full moon to the autumn equinox – has a reputation for being bigger and brighter and yellower than other full moons. That reputation isn’t deserved; the Harvest Moon is not bigger, it’s not brighter, and it’s not yellower than other full moons. But, in autumn, the ecliptic – or path of the sun, moon and planets – makes a narrow angle with respect to the horizon in the evening hours.
On average, the moon rises about 50 minutes later each night, but, due to the autumn angle of the ecliptic, the Harvest Moon comes up near the time of sunset for several evenings in a row around the time of full moon. Around the time of the Harvest Moon, we have what looks like a full moon, rising in or near twilight, for several nights instead of just one.
Tonight’s moon does that, too. There’s a shorter-than-usual time between moonrises on these next few nights. That’s because we’re near the autumn equinox (although not as near as we’ll be at the next full moon, on October 6-7, when the effect will be even more pronounced).
Check out the custom calendar at Sunrise Sunset Calendars, and be sure to click the box for moonrise times. See if you notice that the moonrise in your location is less than 50 minutes later between the night of September 6, 7, and 8 from your location. It will be, if you’re at a temperate latitude in the Northern Hemisphere.
Meanwhile, from temperate latitudes in the Southern Hemisphere, there will be a longer-than usual time between moonrises for the next few evenings.
September full moon is in AquariusThe full moon on the night of September 7, 2025, is located in the direction of the constellation Aquarius the Water Bearer. The moon is roundest on the day when it is full, but the day before and the day after, it appears almost, but not quite, full.
