IR sensors aboard US DOD satellites detected the impact of a
bolide over the Eastern US on 23 July 2001 at 22:19:11 UTC.
The object was traveling roughly East to West.
The object was first detected at an altitude of approximately
82km at 41.5 North Latitude, 75.6 West Longitude,
and tracked down to an altitude of approximately 32 km at
41.3 North, 77.3 West. The impact was simultaneously detected
by space based visible wavelength sensors operated by the US
Department of Energy. The total radiated energy was
approximately 1.27 X 10^12 joules.
