Overview
- Peak occurs on Nov. 5, with local full phase times reported as 8:19 a.m. EST and 6:19 a.m. in Arizona, though the best public viewing is around moonrise on Nov. 4–5 with a clear eastern horizon.
- At roughly 356,980 km (about 221,817 miles) from Earth, the Beaver Moon is identified by astronomy outlets citing the Old Farmer’s Almanac as the year’s nearest and most luminous supermoon.
- As a perigean full Moon, it can appear up to about 14% larger and roughly 30% brighter than a typical full moon, with the horizon “moon illusion” making it seem even bigger.
- This is the second of three consecutive 2025 supermoons, following October’s event and preceding the Cold Moon on Dec. 4.
- The Beaver Moon name traces to North American and European traditions noting beaver activity in late autumn, with bright moonlight likely to reduce visibility of faint meteors during the Taurids before the Geminids peak in mid‑December.
