The events that unfolded in the Ukraine today are probably related to the passage today of asteroid 2012 DA14 through a trajectory lower than many geosynchronous satellites. A body of such size will probably not be alone and will carry with it a cloud of smaller debris in a halo around it that may extend for many thousands of miles.
I'm betting that more meteor strikes will be seen before the day is out or tomorrow coming in the wake of the main body as it passes earth.
