A Meteor's Flash and Boom in Metro Vancouver

Some residents were able to capture a shot of the meteor

Last night just after 9pm, I heard a muffled boom and some minor vibrations.

I knew it wasn't an earthquake but it was very unusual.

Lots of other people on social media thought so too.

People reported seeing a bright flash

Turns out it was a "fireball" meteor about the size of a soccer ball that flew into Earth's atmosphere, causing a bright flash in the sky, followed by two booms in quick succession.

The fireball was seen as far west at Comox, British Columbia, as far east as Merritt, and as far south as Seattle, Washington.

Johanna Wagstaffe, a CBC meteorologist and science reporter said local seismographs showed a spike at around 9.10pm, and that the sonic boom is "classic evidence" of a meteor travelling through the atmosphere.

She noted meteors don't often appear in western North America. "But it's always a big deal when we can visually experience something falling from space."

Wagstaffe explained a sonic boom occurs when an object travels through the upper levels of the atmosphere so fast -- from between 20 to 70 kilometres per second -- that it compresses the air ahead of it and heats up. In this case, the meteor was traveling 33 kilometres per second, or around 119,000 km/h.

A seismograph registered the boom at 9.10pm

The American Meteor Society also confirmed the meteor sighting, and described it as a fireball, as the duration of the flash was too short to be human-made debris, and that it was a natural fireball made of stone, metal, or a combination of both.

It is believed the meteor landed tens of kilometres north of Coquitlam in a heavily forested area, so the chances of finding the fragments are extremely slim. Maybe one day years from now a hiker will discover the fragments? You heard it here first.
