ASTEROID EXPLODES OVER ARIZONA: On June 2nd just before 4 a.m. MST, a small asteroid hit Earth's atmosphere and exploded over Arizona. The airburst shook the ground below and produced a flash of light 10x brighter than a full Moon. NASA says it was a 3-meter wide space rock from beyond the orbit of Mars. Shortly after the explosion, Mike Lerch walked out the front door of his house in Phoenix on the way to work, and this is what he saw:

"At first I thought it was a rocket launch," says Lerch. "Now I realize it was debris from the asteroid." Indeed, the smokey remains were widely visible as they twisted in the winds high above Arizona.
