a total eclipse of the moon on December 21 at 2:40 am. (You may see the time on some sites as UT," or "Universal Time." This is equivalent to Greenwich Mean Time, the standard time for astronomy etc. This NASA page explains the details and conversion to EST and other zones.) The NASA sites listed above are helpful if you want to learn more. According to EarthSky.org there won't be another such eclipse so far north until 2485, so it might be best to catch this one ;-)
If this gets you interested in the moon and astronomy, the online Encyclopedia of the Solar System would be a starting point, and it has a nice article on the moon. We have some great books in our collection too!
