Astronomers from The University of Western Ontario in London, Canada have released footage of a meteor that was approximately 100 times brighter than a full moon. The meteor lit up the skies of southern Ontario two weeks ago and Western astronomers are now hoping to enlist the help of local residents in recovering one or more possible meteorites that may have crashed in the area of Grimsby, Ontario.
"This particular meteorite fall, if any are found, is very important because its arrival was so well recorded. 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," says McCausland. "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."
The fireball was first detected by Western's camera systems at an altitude of 100 km over Guelph moving southeastwards at 20.8 km/s. The meteoroid was initially the size of a child's tricycle. Analysis of the all-sky camera records as well as data from Western's meteor radar and infrasound equipment indicates that this bright fireball was large enough to have dropped meteorites in a region south of Grimsby on the Niagara Peninsula, providing masses that may total as much as several kilograms.
