Fragments of the Tagish Lake[1] meteorite impacted upon the Earth on January 18, 2000 at 16:43 UT after a large meteoroid exploded in the upper atmosphere at an estimated altitude of 30 to 50 km with an estimated total energy release of about 1.7 kilotons. Following the reported sighting of a fireball in the Tagish Lake area in the Yukon Territory and northern British Columbia, Canada, more than 500 fragments of the meteorite were collected from the lake's frozen surface. Post-event atmospheric photographs of the trail left by the associated fireball and U.S. Department of Defense satellite information yielded the meteor trajectory [2]. Most of the stony, carbonaceous fragments landed on the Taku Arm of the lake, becoming encased in ice after landing on the lake's frozen surface. The passage of the fireball and the high-altitude explosion set off a wide array of satellite sensors as well as seismographs.
