WIKIPÉDIA

The Tagish Lake meteorite fell at 16:43 p.m. on 18 January 2000 in the Tagish Lake area in northwestern British Columbia, Canada. Fragments of the Tagish Lake[1] meteorite landed upon the Earth on January 18, 2000 at 16:43 UT (08:43 local time in Yukon) after a large meteoroid exploded in the upper atmosphere at altitudes between 50 and 30 km with an estimated total energy release of about 1.7 kilotons. Following the reported sighting of a fireball in the in southern Yukon 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, coming to rest 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.
