When should I look up? May's full moon, best known as the flower moon, is due to reach its peak illumination Monday, May 12, 2025.

I pick out North America’s celestial highlights for the week ahead (which also apply to mid-northern latitudes in the Northern Hemisphere).

A full moon is referred to as a micromoon when it occurs around apogee, the point in the moon’s orbit farthest from Earth, according to Time and Date. As a result, it can look around 6% to 7% smaller than the average full moon.
