Here's a collection of insane videos of the event, some with the enormous sonic boom: http://www.youtube.com/watch?v=XIAm5hq8WWc http://www.youtube.com/watch?v=b0cRHsApzt8 http://www.youtube.com/watch?v=Np_mpGYSBSA Can anyone translate what they are saying in the first one? You can get a good idea of the new videos being posted using YouTube's "last hour" filter: http://www.youtube.com/results?search_query=%D0%BC%D0%…
A bunch of videos around town and some photos of damage etc. http://oleg-kozyrev.livejournal.com/4468083.html Examples of other meteorite strikes in the past: http://oleg-kozyrev.livejournal.com/4468452.html Damaged zinc plant? https://twitter.com/Dokhrimovich/statuses/302269134685757442 Reuters: http://www.reuters.com/article/2013/02/15/us-russia-meteorit...

I wish we had more information.
Edit: on second thought, it could easily be a fragment, we'll see.

There's a video of two guys driving by the zinc plant: http://www.youtube.com/watch?v=ptnGvd0dmLI
I didn't think the sky could simply open up and rain down hellfire without anybody spotting it beforehand.

While it's moving at great speed, it's really about distance that determines the gap with sonic booms. Speed of sound is ~340m/s at sea level, so using that value with a gap of 27 seconds we can assume the boom originated ~9.1km away from the camera(thus it took 27 seconds for the sound to reach the camera). The distance is probably wrong given the speed of sound is different depending on the altitude. The speed had…
And to be clear, there isn't any one "boom" event with a sonic boom. It is an ongoing event for stationary observers, a pressure front that follows the object and is heard when it passes by you.
The explosion is clearly audible 25 seconds in to this clip: http://www.youtube.com/watch?v=Np_mpGYSBSA
Great video except for the Vertical Video Syndrome [1]. Is that glass breaking right after the shockwave? I wonder what kind of overpressure it generated. eta: ghshephard posted a link to a better video with the clear sound of glass breaking. https://news.ycombinator.com/item?id=5224858 [1] http://www.youtube.com/watch?v=Bt9zSfinwFA

That is an amazing event. I am not sure I buy the meteorite story. Has anyone checked on 2012-DA14 [1] the asteroid that was supposed to cross between the earth and geosync orbit this evening? One conjecture would be it knocked something out of orbit. The air defense stuff is somewhat hard to believe, we don't intercept de-orbiting space junk, much less less hypersonic meteors. Further every missile interceptor that…
I don't get why everyone seems to be running out of (what appear to be) fairly sturdy concrete buildings and into the street. Sure, a building won't protect you from an incoming meteorite of any size, but being indoors might protect from fragments if an incoming meteor hits something else.
It's hard to know what caused the boom if they didn't see something first.

Here's a great dashcam video that captures the meteor arcing across its field of vision and lighting up the scene more brightly than the sun like a nuclear blast (first submitted to HN by dennisgorelik). I almost thought it was a hoax, and even tried to examine the video for signs that it was CGI. http://www.youtube.com/watch?v=tJOJ6B2XOyA The guy doesn't even say anything for a long while, just starts speeding up. e…
