This morning, a small asteroid, which had been discovered only hours earlier, struck Earth’s atmosphere and completely disintegrated over Canada. An automated camera at the CN Tower in Toronto captured the fireball.
Well, here’s a BEAUTIFUL view of the bolide from the camera that looks up at the Tower… pic.twitter.com/cxl1lrVeM8

Astronomer David Rankin found the space rock in survey images taken at Mt. Lemmon, Arizona.
The observations triggered a warning of an imminent impact.
Another #imminent_impactor has been spotted 🤩
Likely less than 1 metre in diameter, this will become a pretty and harmless fireball to observe. #C8FF042
Predicted time of atmospheric entry is 8:26 UTC, over the great lakes. pic.twitter.com/51F2YmtwBu

Seven observatories were able to photograph the sub-meter object before it impacted the Earth’s atmosphere on Nov. 19th at approximately 08:27 UTC over Brantford, Ontario, Canada.
According to the European Space Agency (ESA), this is only the sixth time in history that a global asteroid alert gave astronomers time to observe an incoming space rock before it struck our planet.
“This capability is rapidly improving,” says ESA.
More than 33 eyewitness reports have been submitted to the American Meteor Society from as far south as Maryland in the USA. Most reports are concentrated around Niagara Falls.
Experienced observers say the fireball’s peak brightness was between magnitude -10 and -20. For comparison, a full Moon has an apparent magnitude of about -12.5.
The Minor Planet Center has posthumously designated this asteroid 2022 WJ1.
