A blue moon is a rare second full moon in the same calendar month. We’re lucky enough to have one at the very beginning of this May and one at the very end.

Skies were mostly clear last night, as the moon rose at 8:19 p.m. very close to 99.6 percent full. Tonight, a few high and mid-level clouds are possible as the full Blue Moon rises at 9:17 p.m. Still, solid viewing.

Final cool facts: It’s size appearance in the sky will be smaller-than-usual full moon by ~10 percent. Also, a blue moon only comes around about every two to three years. More reason to enjoy it this weekend!
