Researchers from the University of Calgary studying a meteor that lit up the night sky in November are using footage captured on a CTV Edmonton security camera to try and calculate the path of the fireball.

Alan Hildebrand and his research partner found fragments of the meteorite in Lloydminster almost a months after it fell to the ground.

Hildebrand is now hoping CTV video footage will help him calculate the meteor's trajectory.

"You get a sequence of images and so we'll be able to get the speed that the fireball was moving at and that in turn lets us calculate what orbit it fell from," he said.

A grassroots search for the meteor began after it blazed across the Prairie Sky Nov. 20, 2008.

The group, organized by the University of Calgary, has recovered more than 100 meteorites from the site near Lloydminster, on the border of Alberta and Saskatchewan, and says many more are still out there.

Volunteer searcher Ellen Milley, who is pursuing her master's at the University of Calgary's geoscience department, found the first meteorite fragments on Nov. 27.

U of C planetary scientist Alan Hildebrand said in a written statement there are roughly 2,000 meteorites of 10 grams or more, per square kilometre, in the northern part of the field where the fragments were found.

Altogether, he calculated, there are likely more than 10,000 meteorites on the ground in the area.
