Astronomers from St Petersburg rate the object (without any own observations) at multiple 10,000s tons of mass... if it would be made of rock, this is already achieved at 8000 cubic meters of material (25 meter diameter), iron would already reach this at half the volume (18 meter diameter).
I'd wait for some orbit determination before any conclusions.
Russian space agency Roskosmos has confirmed the object that crashed in the Chelyabinsk region is a meteorite: “According to preliminary estimates, this space object is of non-technogenic origin and qualifies as a meteorite. It was moving at a low trajectory with a speed of about 30 km/s.”
this is a great video of it. First of all you see the trail then hear the windows shatter and multiple sonic bombs. The rock definitely shattered into many pieces. I count at least 20 sonic booms as the fragments decelerate.
I also nearly jump the gun on this one.
My first thought was that a piece of 2012 DA14 was the culprit.
The flightpath of 2012 DA14 was on the same orbital line where this meteor struck
But 2012 DA14 flightpath come from the south east and if I understood it correctly, this meteor moved from the south west to the northeast.
Those silly scientists, with their trajectories, and probability statics and such as. What do they know, amirite?The usual crackpots in a local computer forum are already raging how scientists could declare these events for not connected, if it is sooo obvious that they must be connected. Scientists have no clue.

Saw the mass estimate that it was around 50 tons. If it came at 30 km/s the yield of airburst would be in several kiloton range.
Meanwhile some voluntary smashing of people's own windows, done in hope of a free replacement by the regional government, were reported across Chelyabinsk. Oh well, this is reported by the regional press service...
