Additionally, some locals heard a loud boom and even reported feeling the ground shake, according to Phoenix affiliate ABC 15 , though the Arizona Geological Survey didn't pick up any readings of seismic activity.

Eyewitness Mark Olhava caught the phenomenon on his GoPro dashcam and was flabbergasted by the unique sight.

"We drive trucks all over the country and never saw anything like it," Olhava told weather.com in an email.

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."

"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 he surmised 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."
