Authorities in several Midwestern states were flooded Wednesday night with reports of a gigantic fireball lighting up the sky, the National Weather Service said.**Update** There's more, a new video from youtube (near Cedar Rapids):
The fireball was visible for about 15 minutes beginning about 10 p.m., said the National Weather Service in Sullivan, Wisconsin, just west of Milwaukee.
"The fireball was seen over the northern sky, moving from west to east," said the NWS in the Quad Cities area, which includes parts of Iowa and Illinois.
"Well before it reached the horizon, it broke up into smaller pieces and was lost from sight," the service said. "Several reports of a prolonged sonic boom were received from areas north of Highway 20, along with shaking of homes, trees and various other objects including wind chimes," it said.
It said the fireball was seen across parts of Missouri, Illinois, Indiana and Wisconsin. CNN affiliate WISN-TV said that people in Ohio also saw it.
