Tonight(Oct. 6) the first supermoon of 2025 will rise big and bright into the autumn sky. Dubbed the Harvest Moon — one of the most famous full moons of the year — it is the first full moon of autumn in the Northern Hemisphere, traditionally used to mark the end of the harvest season.
The moon will officially turn full at 11:47 p.m. EST on Monday (3:47 p.m. UTC on Tuesday, October 7) and will appear bright and full on the nights immediately before and after the peak. Dusk on Tuesday will be the best time to see the full moon appear on the eastern horizon, but it’s also worth looking east at dusk on Sunday (Oct. 5) to see the almost-full moon shine just above Saturn, which is about as close to Earth as it ever gets.
