As detailed in
http://skyandtelescope.com/aboutsky/pressreleases/article_946_1.asp There will be a full lunar eclipse Thursday night. Things start at 8:05 PM (CDT) when the moon enters the penumbra - but that doesn't dim things very much. At 9:03 PM (CDT) the moon enters the umbra and the real thing starts. Totality lasts from 10:14 to to 12:17 AM (CDT) and it's completely over at 1:15 AM (CDT).
Usual adjustments for other time zones, though the moon rises already in partial eclipse in the Pacific time zone.
As this is a lunar eclipse, no safety precautions are needed. Stare at the moon all night long if you want!
