The fireball that passed over Edmonton Friday night may have left more behind than experts originally thought.

"There's a good chance meteorites might have fallen," the University of Calgary's Dr. Alan Hildebrand told Sun Media.

Witnesses in Edmonton reported red fragments continuing toward the earth after the intense light of the meteor subsided.

This prompted Hildebrand and Dr. Martin Connors of Athabasca University to review footage from security camera systems to determine the location of the fireball in the sky.

"If the sky is clear, the lights cast a shadow," explained Hildebrand. By measuring the angles of the shadows they were able to calculate where remnants may have landed.

Hildebrand believes fragments of the meteor may be around Redwater, 68 km northeast of Edmonton, especially in the area of Township Road 574 and Range Road 220.

Unfortunately, no one in the area witnessed the fireball or falling debris.

Because they have no exact location, Hildebrand said scientists will rely on farmers in the area to keep their eyes open for chunks of the meteor.

Though it would be best if the pieces were handled as little as possible, Hildebrand isn't picky.

"If one lands in a manure pile, I'll still take it."

He warns farmers to watch their footing since the larger pieces can make deep holes. Meterorites are recognizable by their dark grey or black crust.
