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

Stefan Geens did a nice job computing the trajectory. Shallow grazer!
cool animated gif of shadows moving as meteor passes to give trajectory calculation trajectory to impact picture Geen's trajectory can be displayed in this google earth kmz file. Geen's estimate is that the meteor passed near Chelyanbinsk at 03:15:00 UTC. Meanwhile there was a 6.8 earthquake in Syagannakh Russia at 08:17:00 UTC. link. Interestingly, and coincidentally, this earthquake lies close to the trajectory path of the meteor (maybe 15 degrees off the path?). Compare Geen's trajectory to the google earth location of the quake. The quake was 5 hours later however, which make the quake very likely coincidental and nothing more. If a second meteor had been following the Chelyabinsk meteor, 5 hours later, and impacted near Syagannakh, that would be amazing. Highly unlikely, but it is an uninhabited region, and maybe there were no public reports (one would have to assume if it happened, this putative hit would have lit up the defense grids of both Russia and the US). Still, it might be worth checking if anything unusual happened near Syagannakh (which looks like lake strewn tundra in Google maps). quake link earthquake |
