Scientists are urging people in the Niagara region of Ontario to be on the lookout for debris from a meteorite that hit the area this weekend.
Residents of the area between Toronto and Hamilton were able to see the meteor light up the sky early Saturday morning.
Western University physicist Peter Brown says the meteorite weighed about 500 kilograms and was less than a meter in diameter when it entered Earth’s atmosphere at about 3:25 a.m. Saturday.
He says people living in the area from Toronto to Hamilton heard the sonic boom the meteorite caused because it was moving at about 40 times the speed of sound before breaking up in the atmosphere.
According to Brown, his research group believes that a small fragment of the meteorite reached the southern shore of Lake Ontario, around Grimsby and Vineland, and a larger fragment weighing several kilograms landed north of St. Catharines.
Kim Tate, curator of mineralogy, meteorites and gems at the Royal Ontario Museum, said a group of researchers had surveyed the area over the weekend looking for space rocks, but had found none because of the snow. .
