North Americans could get a glimpse of the Earth shadowing the moon (very) early Saturday — the third in a series of four lunar eclipses that began nearly a year ago. But only those on the West Coast, in the Pacific or Asia will have a chance at seeing the full show.
In Washington, D.C., for example, the penumbral eclipse — a noticeable darkening of the moon's face — will begin sometime at 5:35 a.m. EDT, according to Sky and Telescope magazine. A partial eclipse will begin about 40 minutes later, but the moon will set before totality.
For the West Coast, however, the same progression begins at 2:35 a.m. PDT. The total eclipse starts just before 5 a.m. PDT.
Your ability to see any of it, of course, is subject to the weather. And, for exact times for your location, you should go to the U.S. Naval Observatory's Lunar Eclipse Computer, here.
If you're a little fuzzy on the details on the celestial mechanics involved in a lunar eclipse, we offer this reprise of NPR's Adam Cole explaining it in song form. (Ignore the times he mentions, as they are a reference to last April's eclipse. Enjoy the rest though.)
