Bolide low altitude break up over Russia

A bolide hit the Earth over Russia, breaking up at low altitude, causing a strong shock that reached the ground causing damage.
There are reports of some fragments hitting the ground.

Good summary and videos at The Age

video from Russia Today

the fragments will be valuable and probably show up soon on ebay

there was no shootdown, the breakup is normal when the meteorite gets lower down into the atmosphere.
There are no issues with radiation [sic]

looks like a fairly slow shallow angle impact, detonating with kiloton++ energy below few km altitude - guessing from the video

that'd make it a substantial size meteor - probably well over a ton in weight, over a meter diameter, maybe several meters across.

Call it car size and the weight of a small truck
recovered fragments will give composition, I'm betting rocky chondrite - hope someone is sending some of the fragments to people who know what they are doing

interesting

unconfirmed reports of multiple injuries
- not unlikely given reports of shattered windows and ground shock, hopefully no one was killed

RFLP is an acronym that stands for "Restriction Fragment Length Polymorphism." That's quite a mouthful and once you've said this phrase a few times, you realize why we use the initials instead.
There are 23 new articles in PLoS ONE today.
Have you ever momentarily forgotten the name of a specific place, or person, despite being able to recall many things about the name (for example the first few letters, or the number of syllables)?

You know what's going to happen next, right?

North Korea is going to issue a statement saying that its nuclear-tipped missile test was a complete success, thanking Russia for allowing the test over its own airspace, and warning the United States that the next one is for us.

And then U.S. Senate Republicans are going to filibuster NASA until after they get back from their next long vacation.

15 miles up is "low altitude?"
