Note: This is almost certainly unrelated to the asteroid 2012 DA14 that will pass on Friday. See below for details.
[Let me be clear: This is breaking news, and reports are coming in so fast I can’t keep up. I’ll update this post as I can, but treat everything here as tentative until I can get more information! Note also lots of hoaxes are turning up, like a video of a flaming crater that's actually a flaming pit in Turkmenistan that's been burning for decades (called "The Door to Hell"). Be cautious and be skeptical.]
Dozens of videos are popping up on YouTube, and some are incredible. This one from a car’s dashboard camera shows the meteor coming through the atmosphere.
