Two weeks ago a meteor streaked across the sky over southern Ontario, and now astronomers want to contact anyone within 10 kilometres of Grimsby who may have seen the event.

Researchers at the University of Western Ontario recorded footage of the meteor, and say it was about 100 times brighter than a full moon.

They would like to hear from anyone who saw the meteor on Sept. 25, "heard unusual events at the time," or who found fragments on the ground.

"This particular meteorite fall, if any are found, is very important because its arrival was so well recorded," McCausland, a postdoctoral fellow at Western's Centre for Planetary Science & Exploration, said in a press release.

"We have good camera records as well as radar and infrasound detections of the event, so that it will be possible to determine its orbit prior to collision with the Earth and to determine the energy of the fireball event.

"We can also figure out where it came from and how it got here, which is rare. In all of history, only about a dozen meteorite falls have that kind of record."

Western's camera system caught the meteor as it blazed through the air at nearly 21 kilometres per second over the city of Guelph.
