Meteor sightings were reported across the Valley and the entire state of Arizona Tuesday evening. A bright, green light flew across the Las Vegas, Phoenix and Tucson sky. In southern Arizona, many residents reported seeing the sky light up and then hearing a loud boom and rumble. KTAR's Dr. Sky says the object appears to be a sporadic fire ball.

"We're seeing more and more of the fireballs in our skies but nobody really knows why," Sky said.

Sky explained his theory behind Tuesday's phenomenon. He's says a meteor shower was taking place called the Andromedids.

"It's very possible that this could be material from a distinct comet that's called Beilas comet."

He reported that skywatchers have been seeing bright fireballs and meteors over the past few days.
