First Supermoon of 2025 to Illuminate Skies on October 6
The first supermoon of 2025, known as the Harvest Moon, will appear on October 6, offering a brighter and larger full moon to observers worldwide.
On October 6, 2025, skywatchers will witness the first supermoon of the year, commonly referred to as the Harvest Moon. This event occurs when the full moon coincides with its closest approach to Earth, known as perigee, making it appear up to 14% larger and 30% brighter than when it is at its farthest point.
The term "Harvest Moon" traditionally refers to the full moon closest to the autumnal equinox, which aids farmers in harvesting crops by providing extended evening light. In 2025, this designation falls on the October supermoon, a relatively rare occurrence.
Observers can expect the moon to reach its fullest phase at 11:48 p.m. EDT on October 6 (03:48 UTC on October 7). The moon will be approximately 224,599 miles (361,459 kilometers) from Earth during this time.
This October supermoon marks the beginning of a series of three consecutive supermoons, with subsequent events occurring in November and December. The November supermoon is anticipated to be the closest and brightest of the year.
For optimal viewing, observers are advised to find a location with an unobstructed view of the horizon during moonrise or moonset, when the moon appears largest due to the "moon illusion." No special equipment is necessary to enjoy this celestial event.
