Over the next couple of days, look to the sky, and you might witness the year’s brightest and largest full moon.

The November full moon, commonly known as the Beaver Moon, is set to be 2025’s second supermoon. Here’s what you should know about this special astronomical event.

What is the Beaver Moon?

The term “Beaver Moon” refers to the full moon that appears in November.

Each month’s full moon holds a distinct name, often carrying cultural significance. The November full moon acquired its name from the fact that beavers typically begin taking refuge in their dams around this time of year, according to the . Another potential reason for the name is that this period historically marked the season for setting beaver traps during the fur trade.

What is a supermoon?

A “supermoon” describes a full moon that appears larger and brighter because its elliptical orbit brings it closer to Earth. When the moon reaches its perigee—its nearest point to Earth—it can look up to 14% bigger and 30% brighter than the year’s faintest moon, according to the . Supermoons generally occur approximately three to four times each year.

The previous supermoon was the Harvest Moon, which appeared in October. According to NASA, a third and final supermoon for this year is expected in December.

When and how can you best view the November supermoon?

The Beaver Moon’s maximum illumination will be on Wednesday, November 5, at 8:19 a.m. ET, as per the Almanac. However, it will also be visible on the evening of Tuesday, November 4, and the evening of November 5. You should be able to observe the moon without a telescope or binoculars, though using these instruments can help you discern more surface details.

The optimal way to view a supermoon is from an open, flat area with an unobstructed view of the sky, so be sure to check your local forecast. Locations such as fields, parks, and waterfronts are ideal spots to observe the supermoon. And don’t forget to gaze upwards!
