I haven't heard officially if anything of this meteorite was ever recovered.
Wondering if this meteorite completely evaporated during its explosive entry
much like the Tunguska event. Divers did check the lake and found nothing
but were they "scientist divers", Govt. assigned divers, or ametauer divers
not knowing how and what to look for. For such a destructive and media
covered event nothing I heard has been officially found but I could be wrong

Subject: Re: [meteorite-list] Chelyabinsk: of contrails, bollides and IR
Hello everyone -
I got to watch the Russian videos before all the pop tunes and colorful
Russian expressions were removed. The sanitized compilations are simply
not as good. I would have preferred subtitles being added to them instead.
One of the interesting things is that releases of binding forces, the
bollides, or "implosions" have previously been estimated to occur around 5
kilometers in altitude. If I am viewing the entry contrail in this case
correctly, it looks like this bollide went off around 8 kilometers in
altitude, indicating a pretty friable small impactor.
Given the slow velocities of the shattered glass pieces, what reached the
ground was pretty small. You can be sure that after much delicate dancing,
data will come out and analyzed by the specialists.
In the meantime, infra-red spread estimates from the public videos may end
up providing a first order estimate as to the magnitude of the bollide.
Another interesting thing is that it has generally been assumed that
almost all the momentum was converted into energy in the bollide, but in
this case we can see contrails going off after the main bollide event.

For you folks out there in the field, its -7, so be nice to people; you
might need their help to stay alive. This area has high tech industries,
so don't try to pull any stupid bs stunts either. Remember, the reputation
of all meteorite hunters depend on everyone else's actions, so please
don't p*ss in the soup.
In closing, if this was a CC, and if larger pieces did continue onward,
then it has implications for searching for fragments from other CC
bollides, such as Tunguska.
Finally, I saw one video where a very young lady was having a small piece
of glass removed from her cheek; if she done not get at least a crumb of
this one, shame on all of you.
Good hunting, all
E.P.
