Full Moon Tonight
August's Full Moon rises regally from the east horizon on Wednesday, the 5th, at around 7:40 p.m., close to the time of sunset. This sun-set/moon-rise synchronicity is characteristic of every full moon, because the sun, planet Earth, and the full moon always lie on a more-or-less straight line in space. This time, the alignment is close to perfect. On Wednesday afternoon the moon will graze Earth's partial shadow -- an obscure and virtually unobservable event known as a penumbral lunar eclipse.
