It's a bird, it's a plane, it's...

It flashed across the Okanagan sky like the Vancouver Canucks' playoff chances.

It was there in a moment and gone the next.

People in Kelowna and Vernon emailed Castanet to say they saw something in the night sky, Thursday.

A resident of Black Mountain saw the object falling in a northwesterly direction. It disappeared from sight once it reached the top of the mountain. It appeared about the size of a softball.

It was also spotted by a Vernon resident in the Swan Lake area. Both sightings happened at 9:55 p.m.

Olaf Lutz with the Okanagan Centre chapter of the Royal Astronomical Society of Canada said he hadn't heard of anything falling from the sky last night.

He said it could very well have been a meteor, satellite debris or space debris.

"Look up in the sky for five minutes, and you'll see something," he said.

Passing of the International Space Station was ruled out.
