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

Another measure of the energy imparted by this event:
QUOTE Russian Meteor Shook Ground Like An Earthquake A meteor explosion in the skies above Russia this morning also walloped the Earth, triggering shaking as strong as an earthquake, the U.S. Geological Survey (USGS) reports. Today's early morning blast, centered on the Chelyabinsk region, sent massive tremors through the ground, which were recorded on seismic monitoring instruments around the world. Initial reports pegged the explosion as similar to a magnitude 2.7 shaker, according a seismograph released by the USGS. For comparison, the 1908 Tunguska meteor blast's shock waves, which flattened 80 million trees in Siberia, produced the equivalent of an estimated 5.0 temblor. http://news.yahoo.com/russian-meteor-shook...dF9BRkM-;_ylv=3 --Bill -------------------- |

According to this source, the main trail, or train, is around 320 km long (200 miles). Here it is superimposed above San Francisco, CA, and a 320 km swath of U.S. coastline, for a perspective.
Another one closer in to the city with a portion of the trail through which the horizon beyond is visible: |
