Reports received from across Alberta and B.C. after apparent meteor seen streaking to the south
It didn't take long after a giant fireball lit up the sky above Alberta and B.C. on Monday night for Calgarians to take to social media with photos, videos and posts.
The RCMP got dozens of calls from people across the southern parts of the provinces reporting a bright flash and a sonic boom just after 11 p.m. MT. Reports on social media exploded.

CBC Calgary reporter Drew Anderson was among those who posted about the fireball.
Many were wondering what it was.
Others said it shook houses.
CBC News has not independently confirmed videos posted to Twitter claiming to have captured the spectacle, many on automated security cameras.
The Calgary Eyeopener's astronomy expert, Don Hladiuk, explained what people might have been seeing.
"A fireball is a slightly larger meteor," he said Tuesday morning. "So meteors are grains of sand, space dust, that enter our atmosphere at high velocity and basically light up. Their final moments are a burst of brilliance. A fireball is a larger object."
While there were some reports that parts of the object may have hit the ground — which would then make it a meteorite — this has not been confirmed and a number of landing locations conflicted with others.
Brett Gladman, a professor of astronomy at the University of British Columbia and member of the Meteorite and Impact Advisory Committee of the Canadian Space Agency — formerly a committee of the National Research Council of Canada, told CBC News it was likely a meteor travelling south to north, visible from hundreds of kilometres away.
Gladman said the meteor had a terminal burst near Meadow Creek, B.C. and there is not enough information right now to know if fragments landed.
And searching for fragments won't be easy, as Gladman says the possible area could cover tens of thousands of square kilometres.
