A bright fireball was observed by a network of all-sky cameras across southern Ontario at 11:37pm on Sunday, April 17, 2022 EDT (03:37 202 April 18 UTC).
\nAnalysis of the video data suggests that fragments of the meteor are likely to have made it to the ground near the eastern shore of Lake Simcoe, just north of the town of Argyle.<\/p>\n

meteors. Denis Vida, who specializes in the study of meteors, confirmed that more than a dozen all-sky cameras of Western\u2019s Southern Ontario Meteor Network (SOMN) captured the event north of Toronto late Sunday evening as did a number of citizen
\nscientist-operated cameras from the Global Meteor Network (GMN).
\n\u201cThis fireball was particularly significant because it was moving slowly, was on an asteroidal orbit and ended very low in the atmosphere. These are all good indicators that material survived,\u201d says Vida, an astronomy postdoctoral associate.<\/p>\n

In fact, the fireball was still producing light at just 29 km altitude. Another factor which strongly favours survival of meteorites, includes the very steep entry angle (about 30 degrees from the vertical). \u201cTaken together, these factors suggest many small meteorites have made it to the ground,\u201d says Vida.<\/p>\n

This event is equally important because Western\u2019s meteor research group has good-quality video data of its passage through the atmosphere so they can calculate rock\u2019s origin in our solar system. Preliminary results indicate that the fireball first became visible at an altitude of 90km and travelled almost due north.<\/p>\n

Meteorite fall zone
\n\u201cThe initial mass is believed to have been around 10 kilograms and we would expect tens to hundreds of grams of material on the ground,\u201d says Vida. \u201cMeteorites are of great interest to researchers as studying them helps us to understand the formation and evolution of the solar system,\u201d says Vida.<\/p>\n

Meteorites can be recognized by their dark, often scalloped exterior. Usually they will be denser than a \u2018normal\u2019 rock and will often be attracted to a magnet due to their metal content. Meteorites are not dangerous, but if recovered, it is best to place them in a clean plastic bag or wrap them in aluminum foil. They should also be handled as little as possible to help preserve their scientific value. In Canada, meteorites belong to the owner of the land upon which they are found. If individuals plan to search, they should always obtain permission of the land-owner before venturing onto private land.<\/p>\n

Researchers at Western and the Royal Ontario Museum are interested to hear from anyone in the area of the potential fall who may have heard anything unusual, or who may have found possible meteorites.
