Asteroid Flyby Caught!
July 6, 2006
The asteroid was moving so fast that it created a trail in the telescopic star field during just a 4-second exposure.

One amateur waiting with telescope and camera was Johnny Horne of Fayetteville, North Carolina. He took a series of 4-second exposures with a Meade DSI II Pro camera on a Celestron 11 telescope at f/4 as the asteroid passed through the constellation Cassiopeia, moving from lower right to upper left. He combined a series of his pictures into a 1.9-megabyte QuickTime movie showing the asteroid's motion.
