This happened around 2:30 AM EDT on Wednesday, August 28th. (That is 11:30 PM Tuesday night for Arizona.)
SpaceWeather.com spoke with Bill Cooke from the NASA's Meteoroid Environment Office.
Cooke said "the fireball reached a peak apparent magnitude of -16, about 20 times brighter than a Full Moon, and cast shadows on the ground. This indicates that the meteoroid had a mass of more than 110 kg (240 lbs) and was up to a meter in diameter. It hit the top of Earth's atmosphere traveling 25 km/s (56,000 mph)."
There were reports of people on the ground hearing sonic booms.
Cooke and his team tracked the trajectory (see image below) of the meteor and gathered data from 4 different Doppler radars that showed where pieces may have reached the ground.
Scientists and others are now searching for pieces of meteorite.
