The website Lunar Meteorite Hunters reports sightings of the ball of light down the Eastern seaboard, including Quebec, Ontario, Connecticut, Rhode Island, Maryland, New Jersey, New York, Wyoming and Ohio.
But McGill's meteor expert, Pierre Hudon, says the ball of light could not have been a meteor because when a meteor flies through the sky, the entire sky lights up for several seconds. Hudon says he's received no reports of that happening.
"In Canada we have a network of cameras," said Hudon, "and we didn't receive any reports by camera this morning."
Hudon would not speculate on what the ball of light could be, saying "it could be anything."
The ball of light was captured over the shoulder of weather specialist Colette Provencher during a TVA broadcast at 10:38 p.m. ET Thursday night.
