The moment was captured by a porch camera. It shows the fireball that blazed across Alberta’s skyline after the motion detector activated.

Experts think the fireball may have been a meteor, which created the flashing lights as it fell into the atmosphere.

A porch camera captured this moment as a meteor streaked across Alberta’s skyline after setting off a motion detector.
The front porch footage shows a seemingly quiet evening at Kaitlyn’s house, until a bright light suddenly flashes in between trees in the distance.
Leduc, New Sarepta, and South Edmonton residents reported also hearing the loud boom and the flash.
‘I was getting ready for bed and my notification went off on my phone that there was a motion captured on our front-porch camera, which is weird because we’re out in the middle of nowhere,’ Kaitlyn told Global News.
It looked brighter than it actually was.
“But, then I watched the video again a few more times and realized that it was simply something moving through the sky.”
Edmonton News: She said that she heard something rumbling and it was like a semi truck slowing down.

Meteor is what Astronomers call an “a flash of light” in the atmosphere that happens when debris starts to burn up.
It is also known as a meteoroid. A meteoroid that makes it to Earth is known as a “successful” meteorite.
‘What people got to see would have been a really bright meteor — something we call a fireball or a bolide,’ said Frank Florian, the Telus World of Science director of planetarium and space sciences.
He added that it most likely broke up into pieces and was probably within a 60-kilometre radius from Leduc.
‘Based on what we know, it looks like it’s a fire ball from the entry of a space rock, which we sometimes call a meteoroid coming through the atmosphere,’ said Chris Herd, University of Alberta Professor of Earth and Atmospheric Sciences.
“The loud boom isn’t something that’s very common, and it’s not often.” He said that it suggested the rock had a specific size. Edmonton News doesn’t know how large.
