The May 2025 full moon, also called the "flower moon," officially occurs on Monday, May 12, giving skywatchers who are now enjoying milder conditions a chance to see a micromoon. Micromoons look a bit smaller and dimmer than usual.

The moon will officially reach its fullest phase at 12:56 p.m. Eastern time on Monday, May 12, becoming the fifth of 12 full moons that will shine in 2025. If you look up in the sky Sunday night, you can see the moon at 99% illumination, followed by the completely full moon Monday night and a 99% full moon Tuesday night.

May has a flower moon and the Eta Aquariids meteor shower in store. Here's everything you need to know about both astronomical events.
