FireBall over USA
NASA's Meteoroid Environment Office has upgraded its estimates of a major fireball that exploded over the southeastern USA around 2:30 AM on August 28th. The fireball was 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)." "This is the brightest event our network has observed in 5 years of operation. There are reports of sonic booms reaching the ground, and data from 4 doppler radars indicate that some meteorites may have fallen along the fireball's ground track." (Tennessee)
