If skies would have been clear Tuesday night then skywatchers might have witnessed a bright fireball like this one.

Yes that loud sonic boom and flash of light in the sky on Tuesday night at 7:47 pm EST was indeed a meteor racing across the southern Ontario, eastern Quebec region.

Prof.Peter Brown, a leading expert on meteor physics at the University of Western Ontario reports that infrasonic microphones, part of the USArray network of seismological detectors across the continent detected the series of shockwaves produced by the break up of the meteor as it traveled at supersonic speeds across the region.

“From a very casual examination of the records from five of these stations, it appears the fireball went roughly north-south passing almost right over the Island of Montreal,” said Brown in an email statement.

According to the data, the meteor had energy- on the order of less than a ton of TNT at most, indicating that the space rock might have weighed in the tens of kilograms category, explained Brown.

In comparison, the Russian meteor event in February measured some 20 meters across and had enerrgy equivalent of more than 500 kilotons of TNT.
