If you were awake early Monday morning, you might have noticed a bright green fireball streaking across the Chicago area.
It happened at about 1:30 a.m.
The American Meteor Society is calling it a bolide, which is is one of the largest meteors that can occur, measuring somewhere between 1 meter and 100 meters. Experts believe this meteor most likely came from an asteroid.
“A bolide is a type of fireball that the object, the underlying rock that hits the atmosphere is so big, that it makes this brilliant light, like what we saw in these videos and what people saw last night,” said AMS Operations Manager Mike Hankey. “And then it explodes into thousands of pieces, of little pieces of rock.”
AMS officials say the bolide traveled from southwest to northeast, and probably ended its flight over Lake Michigan between Sheboygan and Manitowoc, Wis. A radar image from National Oceanic and Atmospheric Administration (NOAA) captured the meteor directly over Lake Michigan.
