A scientist says the fireball that streaked above Alberta and Saskatchewan on Tuesday is the biggest and brightest recorded on the Prairies in nearly five years.
Alan Hildebrand with the University of Calgary says the asteroid probably shed meteorites as it flew through the night sky.
Cameras in Calgary and central Saskatchewan captured part of its four-second flight that ended near North Battleford about 8:40 p.m.
Hildebrand says the last fireball to cause such a stir blazed across all three prairie provinces in November 2008.
It's believed that 10-tonne meteor scattered more than 10,000 rock pieces, most of them in farm fields around Buzzard Coulee near Lloydminster.
