Penumbral Full Moon, when two full moons appear in the same month, the moon passes exclusively within the earth's penumbra; very rare, the moon darkens as it darkens the earth, no stars, no sunlight or moonlight. But in August of 2013 it will be two Blue Full Moons for this myth to take place, myth or fact, you decide.
