Overview
- The Moon reaches full phase at 03:48 GMT on 7 October (4:48am BST; 11:48pm EDT on 6 October).
- This full moon qualifies as a supermoon near perigee, making it the largest and brightest of 2025 and the first since November 2024.
- The late timing is uncommon, marking the latest Harvest Moon since 1987, with the previous October occurrence in 2020 and the next expected in 2028.
- Best viewing favors the Northern Hemisphere, including most of India on 6–7 October, with a clear eastern horizon and minimal light pollution recommended.
- Successive moonrises come far closer together than the usual ~50 minutes—about 24 minutes in Boston, 37 in Miami, and 11 in Edmonton—with NASA noting the horizon Moon Illusion can make it appear larger.
