Bright Fireball (Meteorite ?) in USA

The bright fireball reported in the USA at 5:30 am Pacific time on the 19th Feb, in Washington, Oregon and Idaho has turned up on several security Cameras. There is a lot of uncertainty about the nature of the event. It could be a small asteroid or cometry fragment breaking up in Earth's atmosphere, an increasing number of these are being tracked by the automated telescopes, but none this small, reportedly the size of a basketball.
Thousands of tonnes of meteor dust falls to earth every year, but normally it comes in to the atmosphere in sand or rice grain size. Its always exciting to see a big one like this come in. Rest assured, no human in recorded history has been killed by a meteorite, yet !
