This is my 1,000th post and I think it is appropriate that it would be about an asteroid, 2014 AA, the very first one discovered for the new year. I'm writing this as I listen to http://topaz.streamguys.tv/~spaceweather/ hoping to hear the Quadrantids peak which is predicted for 3 p.m. EST today (1-3-14) - see my previous blog.
No visual evidence has been reported of the impact but analysis of infrasound waves from the global network by Dr. Peter Brown, indicates that the asteroid hit the atmosphere on January 2nd (0230 Universal Time) and very likely was destroyed. His analysis indicates a release of 500-1000 tons of TNT energy - a respectable amount of energy for something the size of a car.

We'll see what other asteroid events 2014 brings us.
