From WIRED Magazine’s blog:

In the wee hours of Tuesday morning, the full moon will grow dark and red as it passes through the center of the Earth’s shadow for the first time in seven years.

People west of the Mississippi, who missed out on a less-dramatic eclipse in March, will have the best view of this one: by the time the moon is totally eclipsed, it will already have started to set on the East Coast.

The moon will start getting dimmer around 4am EDT, with peak shadow about an hour and a half later.

I saw the eclipse in March, and it was amazing; the moon’s an easy thing to take for granted, even forget about, until suddenly it’s dark and blood-hued. I can easily imagine how, for most of human history, lunar eclipses were connected to the supernatural and divine. So even if you’re in the East, set that alarm early and stumble outside for a few bleary-eyed minutes. It’s worth it.
