A fireball that lit up the night sky over Alberta and Saskatchewan was a 100-kilogram meteor, experts say.
The space rock’s bright streak appeared low on the Calgary horizon at 8:45 p.m. MT Tuesday night.
Don Hladiuk, an astronomer at the Calgary Science Centre, caught the brief show on a specialized camera.
If you saw the bright flash on Tuesday night, report your sighting at:
He said people in North Battleford, Sask., would have had the most spectacular view.
"This was brighter than the full moon," he said.
"This just lit up the sky. And not only that, for some people, they heard sonic booms. These are the meteorites breaking through the sound barrier — most likely anyway — falling to the ground," he said.
Calgary’s Telus Spark Science Centre is looking for more witnesses, especially people living along the Saskatchewan-Alberta border.
