Tomorrow's full moon will be partially eclipsed as it slips through the shadow that the Earth casts into space.

The bad news is that the eclipse will occur during our daytime, while the Americas are facing the sun. The next total lunar eclipse visible here will be on Dec. 21, 2010. The good news is that, through the magic of the Internet, we'll be able to sit at home, in front of a computer screen, and watch the eclipse unfold on the night side of the planet.

At the height of the eclipse, more than 81 percent of the moon's disk will be in deep shadow. The rest will remain in bright sunlight. That will yield a weird, two-toned lunar disk. The whole event will last about three hours. Web coverage will begin at 3:30 pm EDT Saturday, Aug. 16.

Here are the specs on this eclipse, from Fred Espenak's NASA Eclipse Page.

Here is a pretty darn cool set of animations on the eclipse.

This is a link for an eclipse Webcast from the Netherlands. Here's one from Norway, although the forecast wasn't so great there. But here's one from the Canary Islands, which looked better. Thanks to SpaceWeather.com for the links.
