Many Winnipeggers were stunned by a sudden whitish-green flash in the night sky Tuesday.
It happened at about 10 p.m. and the mystery light was gone as suddenly as it appeared.
Scott Young at the Manitoba Museum said he's not 100 per cent certain about it, but all signs point to the light being a meteorite.
"They slow down so quickly and they heat up so quickly that often they just explode in what's called a terminal burst and that's often a greenish colour," he said.
"So the colour sort of tips me off and also just the speed that this comes over."
If it was a meteorite, it would only be the 14th time in Manitoba history that one has come through the atmosphere in this province, Young said
