Overview
- The Flower Moon, which reaches peak illumination Friday at 1:23 p.m. ET, will appear full after sunset and through the night.
- A second full moon arrives on May 31, creating a calendar Blue Moon, which means two full moons in one month rather than a change in color.
- NASA and the Royal Observatory Greenwich note both May full moons are micromoons near apogee, so they can look a bit smaller and a touch less bright than average.
- Peak timing varies by location, including 17:23 in Argentina and 19:14 in Mexico City, and Argentina’s national weather service warned of cloud cover that could hinder viewing tonight.
- Skywatchers can also look for the Eta Aquarids meteor shower peaking May 5–6 and should seek dark, unobstructed horizons for the best views.
