It was a blinding flash of light in the sky that left many scratching their heads.

Residents across the GTA saw the vivid display overnight and called police, not sure what it was.

Though there's been no confirmation, astronomy enthusiasts in Barrie who caught the bright lights believe it could have been a meteor shower. The reason it may have been more visible than usual is because Venus is brighter at this time of year.

"It didn't look like it was on fire," said Cathy Swatton, who caught a glimpse of the glowing orb. "Red and blue or green or something. It was going so fast across the sky. You didn't have time to videotape it or nothing."

A meteor leaves a trail of light as it passes through the atmosphere and breaks up.
