Western scientists believe bright fireball event near Grand Bend dropped meteoritesA network of cameras directed by Western University observed a bright fireball across southern Ontario at 7:23 p.m. on Wednesday, January 24. Analysis of the video data by Western scientists suggests that fragments of the meteor are likely to have made it to the ground between the communities of Saint Joseph and Crediton, Ontario.
Western's Physics and Astronomy Department runs a camera network that constantly monitors the sky for meteors. Peter Brown, a leading expert in the study of meteors, confirmed that the January 24th event was a meteor as 12 of the all-sky cameras from Western's Southern Ontario Meteor Network (SOMN) recorded a bright fireball over western Ontario.
"This fireball was particularly significant because it ended very low in the atmosphere just to the north of Grand Bend, a good indicator that material survived. In fact, it was still producing light at 24
According to Brown, other factors, which strongly
"This event is very important because we have good quality video data of its passage through the atmosphere and hence know where the rock comes from in our solar system," says Brown. "Meteorites are also of great interest to scientists like me as studying them helps us to better understand the formation and evolution of the Solar System," says Brown.
Preliminary results indicate that the fireball first became visible at an altitude of 75
Brown and the rest of the Western Meteor Physics Group are very interested in speaking with anyone in the area of the potential fall, who may have heard or seen anything unusual, or who may have found possible meteorites.
Meteorites can be recognized by their dark, often scalloped, exterior.
