This month’s full moon over Kansas will appear larger than usual. Why & when to see it
The first “supermoon” of 2025, which is also the harvest moon, will peak over Kansas soon.
Supermoons appear up to 14% larger and 30% brighter than when the moon is at its farthest point, according to National Geographic.
A supermoon is defined as either a new or full moon that occurs when the moon is within 90% of its closest approach to earth, NASA reports, and supermoons are the “biggest and brightest” full moons of the year. “Supermoon” is not an official astronomical term, according to NASA, so definitions vary.
Because the supermoon is the closest to the autumnal equinox, it’s referred to as the “harvest” moon. That’s because this time of year is important for harvesting crops in the Northern Hemisphere.
The harvest moon switches from September to October about every two to three years on average, according to the Farmers’ Almanac, though the last October harvest moon was in 2020.
This month’s full moon is also known as the “moon when corn is taken in,” “big chestnut moon” and “seed moon.” The almanac uses Indigenous moon names, along with monikers from colonial America and other North American sources.
Here’s when to see the first supermoon of the year peak over Kansas.
When will the harvest supermoon peak?
The harvest supermoon will peak over Kansas at 10:47 p.m. Central Daylight Time Monday, Oct. 6, according to the Old Farmer’s Almanac.
AccuWeather’s forecast says the Monday night will be cloudy with the possibility of thunderstorms in Wichita, with a low of 53 degrees Fahrenheit. The moon generally appears full the day before and after its peak illumination. For those planning to stargaze the night Tuesday, Oct. 7, the skies should be clear, with a low around 53.
The moon will rise over Wichita at 6:45 p.m. Monday, according to online clock Time and Date.
When to see more full moons in 2025
After the harvest supermoon, stargazers will have two more opportunities to see a full moon this year, and both will be supermoons. Here’s when to look, from Astronomy.com:
- Wednesday, Nov. 5: Beaver moon
- Thursday, Dec. 4: Cold moon
The Kansas Astronomical Observers will host a “moon festival” event from 7 to 9 p.m. Monday at Newman University’s Gorges Atrium to view the full moon, planets and more.
