There are some pretty good graphics of the red total lunar eclipse coming up December 20/21 (on the winter solstice) at the above link.
Quote from above link:
"It will be the first total lunar eclipse in nearly 3 years, the last being on February 20, 2008."
There also won't be another red total lunar eclipse (for North America) until 2014 when there are a series of eclipses related to Jewish feast dates that Mark Blitz talked about (see next link). If these have something to do with heralding the middle of the tribulation, wouldn't it be interesting if this December eclipse heralded the rapture.
Here is some more discussion at another board about this total lunar eclipse, sounds kind of unique:
The sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the LORD.
Revelation 6:12-13 (New King James Version)
Sixth Seal: Cosmic Disturbances
12 I looked when He opened the sixth seal, and behold,there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. 13 And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind.
