September's Harvest Moon rises this weekend near a bright Saturn

September's full moon, known as the Harvest Moon, reaches its peak on Saturday, September 26, 2026, at 16:49 UTC, or 12:49 p.m. ET, the BBC and USA TODAY's 10Best report.

The Times of India reports that Saturn will appear near the moon as it rises in the east shortly after sunset, with the fainter planet Neptune forming a wider triangle with the pair, though Neptune needs binoculars or a telescope to spot.

Why this full moon carries the harvest name#

The Harvest Moon is simply the full moon that falls closest to the September equinox, which occurred on Tuesday, September 22, according to the BBC and The Sunday Guardian. When the closest full moon lands in October instead, as it did in 2025 on October 7, that one takes the title, BBC Sky at Night Magazine and skyatnightmagazine.com note.

Around the equinox, moonrise times stay nearly the same from one night to the next, unlike other times of year when the moon can rise up to an hour later each night, skyatnightmagazine.com explains. That meant several consecutive evenings of reliable bright moonlight, which historically helped farmers work later into the night gathering crops, the BBC and skyatnightmagazine.com report.

The Royal Observatory Greenwich also lists Corn Moon as another common name for September's full moon, tied to crops traditionally harvested this time of year, the BBC notes.

Saturn's good timing and the moon's low-horizon color#

Saturn is especially well placed this month because it reaches opposition on October 4, when Earth passes directly between the planet and the sun, making Saturn visible for most of the night and relatively bright, the Times of India reports.

If the moon is caught low near the horizon as it rises, it can appear yellow, orange or even reddish, the BBC reports, because its light travels through more of the atmosphere, scattering shorter blue wavelengths and letting warmer colors through.

UK forecasts point to drier, brighter conditions across parts of England, with cloud further west and rain expected for Scotland and Northern Ireland by evening, the BBC reports, putting the best chance of clear skies in southern and eastern parts of the country.

How the date shifts by time zone#

The exact full moon falls on September 27 in Japan, China and Australia, while it lands on September 26 across much of the world, The Sunday Guardian reports, though skywatchers do not need to observe it at the precise peak time since it looks essentially full on the surrounding nights.
