Fireball Detection

On 18 January 2000, sensors aboard DOD satellites detected the impact
of a meteoroid at 16:43:43 UTC near Whitehorse in the Yukon territory,
Canada. The object detonated at an altitude of 25 km at 60.25 degrees
North latitude, 134.65 degrees West Longitude. Optical sensors detected
the same event at 16:43:42 UTC. The event  lasted 2 seconds at 1 micron
wavelength.  Estimates of total radiated power (assuming a 6000K 
Blackbody model) are 1.1 x 10 exp 12 Joules.

Assuming a 10% energy conversion, this corresponds to approximately 2-3
kT TNT equivalent total equivalent energy.
