Don't go outside tonight!

The moon will bleed and you'll get some on you! 
Actually it's just a lunar eclipse and quite harmless unless you're a superstitious lout.. 
Sometime around 11:30 the moon should turn red, about the color of an electric burner just getting hot enough to glow..

From a part of an article in the NYT about the eclipse..

Quote:When the moon is about three-quarters of the way into the umbra, it should start lighting up with a reddish hue, “like your electric range just when the coils begin to glow,” Mr. Rao said. At 11:29 p.m., the moon will be in the deepest portion of the Earth’s shadow and the total eclipse will begin in earnest. The eclipse will peak shortly after midnight, at roughly 12:12 a.m., and remain that copper color until after 1 a.m. The moon will leave the umbra at 1:56 a.m., regaining its pearlescent hue as the work week begins.Viewers farther west won’t have to strain to stay up quite as late, with the most stunning views of the red moon beginning about 8:29 p.m. Pacific time, the peak occurring just before 9:12 p.m., and the total eclipse ending by 9:54 p.m. Observers in Hawaii will be able to see the moon rise looking like a reddish ball, Mr. Rao said, while those in Europe and Africa will view the opposite effect, watching the moon drop below the horizon during the total eclipse.The quirks of celestial mechanics mean that totality — when the moon is blood red and in the deepest shadow — lasts longer than average, roughly 1 hour and 25 minutes, giving skywatchers ample opportunity to savor the event. This makes it the longest total lunar eclipse visible for much of the United States since August 1989.

Last solar eclipse a few years ago I was almost directly under it here in South Carolina.. That was pretty cool. The temperature dropped about 15 degrees for about 10 minutes or so. This time, a lunar eclipse will last a bit longer, several hours since the earth is much larger than the moon..
Just in case you're not familiar with the differences between lunar and solar eclipses.. For solar the moon covers the sun from earth. With a lunar the earth covers the moon from the sun..
Enjoy if you have clear weather.
