Is it a bird, a plane, or perhaps a meteor?
Sidney resident Liz Giles woke up Wednesday (March 5) morning to the sound of her doorbell camera, not knowing what she'd see next.
"I got the sound notification at 6:07 a.m. on Nest and thought I would've seen a bird or one of my dogs," she says.
The sight of a bright flash of light streaking across a row of houses in her neighbourhood on Amelia Avenue caught her off guard. In the video, you can hear "electrophonic" sound simultaneously with the fireball blazing through the sky.
"I was shocked, I thought it was a comet," Giles added.
She shared the video on the local Facebook community group to see if anyone else had seen it, unsure of what she had just witnessed.
"At first glance it looks like a bolide B次元官网网址� a large enough chunk of meteoritic material to make a visible fireball rather than a normal shooting star," says Jon Willis, a professor in the University of Victoria's Department of Physics and Astronomy. "As the chunk breaks apart you get that kind of flaring that you see in the video."
One comment on Giles' Facebook post reads: "Likely Starlink satellite burning up upon re-entry. Space X is replacing the older generation satellites, there are over a hundred being 'decommissioned' by dropping them from orbit."
Group members noted how the trajectory indicated that it was ascending into the sky, which is the opposite of how most meteors, fireballs or shooting stars enter the Earth's atmosphere.
Professor Willis, however, says it looked like it was crossing at a low angle.
Giles has already reported the fireball sighting at .
