Flash in sky over Bay Area creates stir online

CONCORD, Calif. (KGO) -- A strange light in the sky lit up Twitter this morning.

A Concord resident captured pictures of the mysterious fireball around 6 a.m. The image showed the unusual object streaking across the sky.

People reported seeing the flash from Los Angeles all the way to Oregon.

Astronomers at Chabot Space and Science Center in Oakland weren't quite sure what it was, but they are sure it wasn't space aliens.

"We don't know what it was," Astronomer Ben Burress said. "One of our experts, looking at a video that was taken, said he didn't think it looked quite like a meteor, but it was really too faint to tell. It could have been a piece of space junk."

Chabot astronomers are waiting for NASA to report if any space junk fell to earth Friday.

In related news, scientists said Wednesday's solar flare will cause Aurora Borealis lights in the northern United States this weekend.
