Check all the usual news sources for information and videos of the massive meteor event over Russia this morning. I will links and more information when I get the chance.
Note: this is almost certainly unconnected with the flyby of asteroid 2012 DA14 tonight.
UPDATE: here's some links to the main stories about the meteor around the web.
Emily Lakdawalla at The Planetary Society has a comprehensive post with links to many of the videos and posts around the web.
Universe Today is conforming that the event is unrelated to the asteroid 2012 DA14 pass this evening. The post also contains some excellent satellite images of the event.
As usual Phil Plait at Bad Astronomy has a great summary with more videos and links of the event.
