Beaver Supermoon to Illuminate Skies as Year's Largest and Brightest Full Moon
The Beaver Supermoon, the largest and brightest full moon of 2025, will reach peak illumination on November 5, offering optimal viewing opportunities on the evenings of November 4 and 5.
The Beaver Supermoon, the largest and brightest full moon of 2025, will reach peak illumination at 8:19 a.m. EST on Wednesday, November 5. As the moon will be below the horizon at that time, optimal viewing opportunities will be during the evenings of November 4 and 5.
This event marks the second in a series of three consecutive supermoons concluding the year. A supermoon occurs when a full moon coincides with the moon's closest approach to Earth, making it appear up to 14% larger and 30% brighter than when it is at its farthest point.
The term "Beaver Moon" is traditionally associated with November's full moon, named for the time when beavers are actively preparing for winter.
For optimal viewing, consider visiting designated Dark Sky Parks, which offer minimal light pollution and clear night skies. Notable locations include Cherry Springs State Park in Pennsylvania, Natural Bridges National Monument in Utah, and Goldendale Observatory State Park in Washington.
Observers are advised to check local moonrise times and weather conditions to plan their viewing experience. The next supermoon is expected on December 4, 2025.
