Flower Moon on May 1: a micromoon glow with a Blue Moon finale

May’s Flower Moon will be fully illuminated at 1:23 p.m. EDT on May 1 as it sits near apogee, appearing smaller as a micromoon about 29.72 arcminutes across; a rare Blue Moon follows later in May on the 31st, meaning two full moons in one calendar month. As night falls, look for Venus at sunset with Jupiter above it, and Spica and Arcturus higher in the sky, while Rayleigh scattering may give the Moon a yellow-orange hue as it climbs and sets.
