October’s Harvest Supermoon Rises as Artemis II Readies for Launch

Skywatchers are in for a treat Monday night as the first supermoon of 2025 rises along the horizon. October’s full moon, known as the harvest moon, will reach its peak fullness around 11:48 p.m. ET Monday, remaining visible into early Tuesday.

A Moon with Historical Significance

The harvest moon, the full moon nearest the autumnal equinox, has historically aided farmers by providing bright nighttime light during harvest season. Its arrival this week offers both a stunning celestial display and a nod to tradition.

What Makes a Supermoon Special

This October moon is the first of three consecutive supermoons this year. Supermoons occur when the moon reaches perigee—its closest point to Earth—making it appear slightly larger and brighter than usual. “It’s a subtle effect, but regular observation can reveal the moon’s changing size over time,” said Noah Petro, project scientist for NASA’s Artemis III mission.

Looking Ahead: Humans and the Moon

October’s harvest moon comes just weeks after NASA announced its newest class of astronauts. Early next year, a crew of four will fly on Artemis II, a mission set to circle the moon. “What makes the moon coming up on October 6 so special is the connection to Artemis II,” Petro noted. “Soon, we won’t just be looking at the moon—we’ll have humans visiting it.”

A Celestial Reminder

Whether clear skies arrive Monday or Tuesday, the harvest supermoon offers several nights to marvel at its glow. Observers are encouraged to enjoy not only this week’s display but the moon’s subtle changes over the coming months.
