A celestial event will begin within a matter of hours after posting, so this won't be read until afterward by most. Sorry about the delay. I won't be able to see it here in Silicon Valley due to the weather.
This is a very rare celestial event, a lunar eclipse occurring on the day of the Winter Solstice. The numbers of the date are interesting enough to make this a day worth watching for signs. As for what kind of signs we should particularly watch for I can't say because I have no particular insight. The date numbers do however sum to 9 as by 3*3, which suggests the theme of the mark of the Beast triple-helix DNA transformation. 1+2+1+2+2+0+1+0=9 12/21/2010 1+2/1+2/2+0+1+0 = 3/3/3/
RARE LUNAR ECLIPSE: The lunar eclipse of Dec. 21st falls on the same date as the northern winter solstice. Is this rare? It is indeed, according to Geoff Chester of the US Naval Observatory, who inspected a list of eclipses going back 2000 years. "Since Year 1, I can only find one previous instance of an eclipse matching the same calendar date as the solstice, and that is Dec. 21, 1638," says Chester. "Fortunately we won't have to wait 372 years for the next one...that will be on Dec. 21, 2094."
WHEN TO LOOK: The total eclipse lasts more than an hour from 02:41 am to 03:53 am EST on Tuesday morning, Dec. 21st. Any time within that interval is a good time to look. For other time zones, consult Shadow & Substance's animated eclipse.
