This is a Meteor Screaming Over Tennessee at 56,000 MPH

How big was it? It was 20 times brighter than the Moon before breaking apart (we hope).

From NASA's Watch The Skies blog:

Early Wednesday morning, at 3:27:20 AM Eastern Time, a piece of an asteroid, about 2 feet in diameter and weighing over 100 pounds, entered Earth’s atmosphere above the Georgia/Tennessee border, just south of Cleveland. The meteor was moving northeast at 56,000 miles per hour, and began to break apart north east of Ocoee, at an altitude of 33 miles. A second, fragmentation occurred less than half a second later, at an altitude of 29 miles. NASA cameras lost track of the fireball pieces at an altitude of 21 miles, by which time they had slowed to a speed of 19,400 mph. Sensors on the ground recorded sound waves (“sonic booms”) from this event, and there are indications on Doppler weather radar of a rain of small meteoritic particles falling to the ground east of Cleveland, Tennessee.

[Pith apologizes for the WalMart pre-roll ad at the beginning of the Space.com video player. But they did slow it down, label the Moon and make it a lot better than the 4-second clip NASA stuck on YouTube.]
