Tonight the sky holds no moon. Or rather, the Moon is there — she has not gone anywhere — but she has turned her lit face entirely away from us, merging with the Sun so completely that she becomes invisible to the naked eye.
Look up tonight and you will find the Moon wearing roughly half her face in light — but that light is fading. The Last Quarter Moon arrives as a precise midpoint between the fullness we have already passed and the darkness still ahead.
Tonight, look up. The Moon is full — completely, perfectly full — sitting directly across the sky from the Sun and catching every bit of its light. This is the midpoint of the lunar cycle, the moment of maximum illumination, the peak before the slow turn back toward darkness and rest.
