Tonight's lunar eclipse

Watch it. Seriously. It's visible almost all over the world. Here's how it's going to happen (All times are based on viewing from Easton, PA [W075° 13', N40° 41']; you can get your times from the Lunar Eclipse Calendar, provided by the U.S. Navy):

The moon enters penumbra tonight at 20:05 EDT and then enters umbra (the "start" of the eclipse) at 21:14 EDT. The eclipse proper (also known as totality) will last from 22:23 EDT until 23:44 EDT. The moon will leave umbra (the "end" of the eclipse) at 00:53 EDT tomorrow morning and finally will leave penumbra at 02:02 EDT.

It's going to be good, especially if you have clear skies. The next Lunar Eclipse will be on 24 April 2005, which is ten days after the next total solar eclipse!

On an unrelated note, this is the first recorded lunar eclipse (partial or total) to happen during a World Series game. This is a record in itself, but it also holds the potential for being the night the Boston Red Sox break their 86-year stretch with no World Series wins. But more on that after the game.
