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.
