Astronomers are still reviewing the source of the light, though some are convinced it was a meteor.

"It would appear that a meteor lit up the skies over Phoenix this morning around 4 a.m.," Kevin Witts, secretary of the Phoenix Astronomical Society told weather.com in an email."The flashes of light and subsequent explosive sounds would certainly indicate a meteor entering the atmosphere. I did not witness it personally but have viewed a few video captures from various security cameras and, in my best judgment, this was a meteor entering the atmosphere."

Local eyewitnesses took photos of smoke trails from the mysterious flash.

"I will continue to monitor information regarding this," he added. "Undoubtedly, there will be more videos surfacing over the next few hours as people realize that they may have captured something."

Josh Bangle, communications manager at Lowell Observatory in Flagstaff, told weather.com that hesurmised the object could have been man-made space debris.

"To the best our our knowledge right now, it appears to be a meteor or 'Space Junk,' around the size of a baseball,"Bangle explained. "I am not sure if any of our telescopes picked it up."
