Pictures and Videos Capture Canadian Fireball from Sept. 25, 2009

A brilliant fireball seen over Ontario, Canada on September 25, 2009 was captured by seven all-sky cameras of the University of Western Ontario's Southern Ontario Meteor Network (SOMN.) The fireball was seen widely by observers throughout southern Ontario and adjacent areas. The fireball was first detected by Western's camera systems at an altitude of 100km, and moving southeastwards at 20.8 km/s. From the data collected, the researchers believe the meteoroid was initially about a meter wide, or about the size of a child's tricycle. At its brightest, the fireball was approximately 100 times as bright as the full moon.

The event occurred at 9:03 pm local time on Sept. 25, or 01:03 UT Sept. 26.

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.
