Calgarians awoke to a fire in the sky early Wednesday morning.

Alan Hildebrand, co-ordinator of the Canadian Fireball Reporting Centre, said 20 people reported seeing a fireball, an exceptionally bright meteor, streak across the sky just before 7 a.m., lasting for several seconds before breaking up into fragments.

Reports were made from the Calgary area, Medicine Hat, Lethbridge, Pincher Creek and other areas, he said.

"It had to be a bright one for everyone in the Calgary area to see," Hildebrand said.

He estimated remnants of the meteorite landed about 400 km south of Calgary somewhere in Montana about two minutes after it appeared as a ball of fire.
