November 26, 2008 - Canadian Fireball A 10-Ton Space Rock.
“At least half a dozen infrasound stations ranging from Greenland to Utah,
including Canada's Lac Du Bonnett, Manitoba and Elgin Field, Ontario stations,
recorded energy from the fireball's explosions. The indicated energy is approximately
one third of a kiloton of TNT.” - Peter Brown, Ph.D., Univ. of Western Ontario
Universe Today reports: “The search is on for fragments of a 10-ton rock that lit the sky over western Canada last Thursday evening. Scientists estimate that at the time it hit Earth's atmosphere, the asteroid fragment weighed approximately 10 tons and was probably about the size of a desk. It exploded with the force of 300 tons of dynamite, and hundreds of fragments of the meteorite weighing more than 50 grams (1.76 ounces) are likely strewn over a wide area. The speed of entry was relatively slow, about 14 kilometers (8.7 miles) per second, well below the average 20 kilometers (12.4 miles) per second of most meteorites, said University of Calgary researcher Alan Hildebrand.”
