Suspected space junk from satellite launch puts on light show over southern B.C.

Falling lights over the West Coast of North America are believed to be the remains of a rocket used by SpaceX.

A cluster of bright, falling lights lit up the skies over B.C.'s South Coast and much of the U.S. Pacific Northwest on Thursday night, the suspected result of rocket debris burning up as it re-entered the atmosphere.

Videos of the phenomenon were posted on social media by residents of the Seattle area, Oregon and B.C.

On Vancouver Island, the Saanich Fire Department tweeted that it had "received reports of flames in the sky" from multiple callers.

"We are much better at investigating fires on earth. The cause of this fire in the sky is still under investigation," the fire department joked.

Jonathan McDowell, an astrophysicist at Harvard University, tweeted that the cause appeared to be the remains of the second stage of a Falcon 9 rocket used by SpaceX to launch a satellite earlier this month.

The U.S. National Weather Service in Seattle has said there is not expected to be any impact on the ground.
