Overview
- The moon will reach peak fullness at about 4:45–4:46 a.m. EDT on Sunday, May 31, with the most dramatic naked‑eye sight occurring at moonrise on the evening of Saturday, May 30.
- NASA and EarthSky report the lunar disk will be near apogee at roughly 252,334–252,360 miles from Earth, making this the year’s most distant full moon and a true micromoon.
- Because it occurs near apogee the moon will appear slightly smaller and dimmer—commonly cited as about 6–7% smaller than an average full moon—though the difference is subtle to unaided viewers.
- The term blue moon here means the second full moon in a single calendar month and not a color change except in rare cases when atmospheric dust or smoke scatters light.
- Local weather and horizon clearance will determine who sees it in person, many groups will provide livestreams and photo tips, and the next calendar blue moon is Dec. 31, 2028 with some outlets noting an uncorroborated 2053 repeat of this exact blue‑micromoon coincidence.
