Explosion a meteor, astronomers say
Reno - Astronomers say a loud explosion heard across a large swath of Nevada and California on Sunday morning was likely caused by a meteor.
The sound of the explosion around 08:00 prompted a flood of calls to law enforcement agencies on both sides of the Sierra Nevada in the two states.
The explosion rattled windows and shook houses from Reno to Winnemucca in Nevada, and from the Sacramento to Bakersfield areas in California.
Some people in the two states reported seeing a fireball streak across the sky at the same time.
Dan Ruby of the Fleischmann Planetarium at the University of Nevada, Reno, said the reports indicate the meteor broke up above Earth somewhere over the Sierra southwest of Reno.
There were no reports of earthquakes at the time.
