Large fireball scattered a great deal of meteorites throughout southern Ontario

When you reside in Ontario, hold your eyes peeled for “suspicious rocks.”

On Sunday (April 17), skywatching cameras within the Canadian province recorded an enormous fireball that probably produced tens to lots of of grams of meteorites. Astronomers predict they’d have fallen on the japanese shore of Lake Simcoe, north of the city of Argyle.

“This fireball was significantly important as a result of it was shifting slowly, was on an asteroidal orbit, and ended very low within the environment. These are all good indicators that materials survived,” Denis Vida, an astronomy postdoctoral affiliate at Western College who focuses on meteors, said in a university statement.

Greater than a dozen all-sky cameras of Western’s Southern Ontario Meteor Community (SOMN) recorded the occasion, which occurred at 11:37 p.m. EDT native time (0337 GMT on April 18). Cameras belonging to the International Meteor Community (GMN), that are operated by citizen scientists, additionally captured the meteor.

Astronomers have used the footage to find out that the fireball grew to become seen at an altitude of round 60 miles (90 kilometers), traveled due north at a pointy angle simply 30 levels from vertical, and continued to burn as little as 18 miles (23 km) in altitude. “Taken collectively, these components counsel many small meteorites have made it to the bottom,” mentioned Vida.

As such, Western College and the Royal Ontario Museum are asking residents within the space of the suspected meteorite fall zone to report any “suspicious rocks” they might discover by sending an e mail to (Value noting — in Canada, meteorites technically belong to the proprietor of the land on which they fall.)


Meteorites usually have a darkish colour and a scalloped texture, and they’re additionally fairly dense. When you discover one, retailer it in a plastic bag or wrap it in aluminum foil — the meteorite itself poses no hazard to people, however scientists want to maintain them as uncontaminated as attainable.

“Meteorites are of nice curiosity to researchers as learning them helps us to know the formation and evolution of the photo voltaic system,” Vida mentioned.
