Brilliant Fireball Over Lake Ontario
On Sept. 25, 2009 at 10:03 p.m. EDT (01:03 UT Sept 26), seven all-sky cameras of Western’s Southern Ontario Meteor Network (SOMN) recorded a brilliant fireball in the evening sky over the west end of Lake Ontario. This event is representative of a fireball which produces meteorites, in this case those falling near the town of Grimsby, Ontario. Fireballs occur fairly often – though they often go unnoticed due to weather or time of night – but meteorite droppers such as this are rare — about once a month over North America.
