Looks like a small meteoroid decided to spoil 2012 DA14's big day by exploding over Russia...

I noticed in the different clips shown the degree of camera saturation varied quite a bit. Some of the slower responding imagers totally whited out, and others seemed to have AGC circuits that tried to follow the illumination level.
I was wondering if any photo analysis has been done yet to determine a decel rate along the path for the rock. It would be interesting to have some idea what it withstood before the fragmenting started. And maybe decel, heating, and turbulence weren't the only effects on it, maybe it was aerodynamically asymmetrical and the slipstream was starting to spin it up some ? |
