Here's the Ars Technica article on the event:

That actually makes them more likely to be authentic.
The reason I mentioned it was that one feed had a date of last year. The tracks look very similar so they appear authentic.

I would have thought by now most would have accurate clocks. Cell phones are and police dash cams should be synced to GPS, with millisecond accuracy. Digital security cams are on networks that should sync to an internet time server every week or so and be accurate to a few seconds.

Standalone cameras are still a crap shoot but I wouldn't expect to see many on a quick-draw event.

Many of the videos are from car dash-cams, everybody in the fussr has them because of the police and psychopath drivers.

Phil Plait is collecting videos and information, and seems to have a pretty good summary of what's known so far.

This video shows the train in high detail with good audio of the sonic boom sequence. http://www.youtube.com/watch?v=0ozSq3yEm3g

That was one of the videos I have seen earlier.

Notice the bang comes around 30 sec - while the explosion didn't have to be exactly overhead, it was at least 10 km from the guy with the camera.

My understanding is that most of those injured are not victims of the direct meteorite hit, but of the shattered glass.

REDDITORS said the image came from Neil's feed.

NASA is stating that the tracks are completely different.
'A man' on the radio said that one track is North South and the other is East West so just a coincidence. I hope we have no coincidences in the UK.

I'd like to see more confirmation, but here they've upped the size estimate by near an order of magnitude and the energy estimate by close to two:
The object that caused the Russian fireball, which damaged hundreds of buildings and wounded perhaps 1,000 people in the Chelyabinsk region, was originally probably about 50 feet (15 meters) in diameter and weighed roughly 7,000 tons, said Peter Brown, director of the Center for Planetary Science and Exploration at the University of Western Ontario in Canada.

From multiple sensors using multiple technologies, a best initial estimate of the total energy of the event is about 300 kilotons of TNT-equivalent

[edit] and the speed estimate to 40,000 mph (18km/s).

So, I've gathered from this that we never saw this coming. I wonder if this is going to add impetus to develop a planetary defense system against this sort of thing......

I can see several reasons why a planetary defense system would not be feasible against meteors.

I came across the website of the American Meteor Society and noticed that the number of reports of 'fireballs' increased from zero in 2004 - 2006 to 2219 in 2012..

Here is the full result



Now which of the following is true?:

A. it's unreliable/fake;
B. armageddon 12-21-12-hype;
C. it merely reflects the profileration of the site;
D. Earth is actually entering a dirty piece of the cosmos
E. a bit of all of the above?
