I just saw this from the Planetary Society:
Join Planetary Society Director of Projects Bruce Betts for live webcast coverage of the encounter with Asteroid 2012 DA14. This 45-meter asteroid will pass within 27,000 kilometers of Earth. Also on hand will be the host of Planetary Radio, Mat Kaplan.

I will only get to see a bit of it since I will be on the road for part of this time.
Enjoy!
