02, 2013 - SPACE - 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.
Lead researcher Bill Cooke
says "the fireball reached a peak apparent magnitude of -16, about 20
times brighter than a Full Moon, and cast shadows on the ground.
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," he continues.
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." (Note: The city in the ground track map is
Cleveland, Tennessee, not Cleveland, Ohio.)
An initial calculation of the fireball's orbit suggested it might be a fragment from a Jupiter family comet.
Improved estimates of the orbital parameters point to a different kind of object: a main belt asteroid.
meteorites are recovered from the Tennessee countryside, their chemical
composition will tell researchers more about the origin of the
