People across western Canada were treated to a light show yesterday evening that may have come from outer space.From Alberta to Manitoba last night, people phoned in reports of multi-coloured lights and fireballs that some suspect came from a meteor.Police were flooded with calls about the sightings.Also a police dash cam captured the event.The RCMP in Lloydminster, on the Alberta-Saskatchewan border, had to issue a press release asking people to stop phoning.The academic community was also buzzing with the reports and experts are now hoping the meteor has left its mark on earth.But scientists say it will take time to find out whether meteorites fell from the sky since they haven't yet pinpointed the fireball's exact location.Meteors usually drop stones within a radius of a few kilometres.
