Residents in the northern Midwest reported a bright light streaking across the sky...And of course people lit up Twitter with their videos.
Many of the accounts came from users located in the Detroit metropolitan area.
Video showed a sky briefly illuminated, before a loud crash.
Some users speculated that the phenomenon was a meteor.
"I just saw a big ol' ball of fire falling, and I started screaming," Barbara Dwyer of Decatur, Mich. told Sinclair station WWMT. "It scared the heck out of me."
The Kalamazoo County Sheriff’s Office and the Calhoun County Dispatch office both said they’ve been fielding numerous calls about a fireball in the sky.
"I just saw a big ol' ball of fire falling, and I started screaming," Dwyer said. "The arrow that followed behind was outlined, like in red. Like a big ball of flames shooting across the sky.
"I've seen meteor showers. It didn't look like a meteor. it just looked like a ball of fire flying across the sky. It had a tail on it."
The National Weather Service has yet to confirm what the event was.
UPDATE - Dept. of Homeland Security tells CBS that the incident over the skies of SE Michigan (and elsewhere in the Midwest) around 8:08 p.m. was a "fireball #meteor." No indication of any damage on the ground. Steady stream of traffic tipster calls for the past hour. Whew!— WWJTraffic (@WWJTraffic) January 17, 2018
