Calgary - People in Alberta and Saskatchewan spotted a brilliant green fireball streak across the sky early Tuesday morning.

University of Calgary geologist Alan Hildebrand says about a dozen witnesses have reported the sight to the Canadian Fireball Reporting Centre.

He says the meteorite, weighing between 10 and 100 kilograms, broke into pieces southeast of Calgary about 6:30 a.m. local time.

He says it likely burned up before hitting the ground.

Last November, a rare 10-tonne meteorite as bright as the sun left thousands of pieces scattered in a farming area east of the Saskatchewan-Alberta boundary.
