A bright green fireball illuminated the sky over Illinois and Wisconsin at 07:25 UTC (01:25 CST) on February 6, 2017. It was captured by numerous cameras.
The American Meteor Society received over 170 eyewitness reports by 09:40 UTC and they are still coming in. Some of them said sound and fragmentation was associated with the event.
The green fireball was seen primarily from Illinois and Wisconsin but witnesses from Michigan, Indiana, Ohio, Iowa, New York, Kentucky, Minnesota and Ontario also reported the event.
The preliminary estimated trajectory plotted from the witness reports shows the meteor was traveling from the Southwest to Northeast ended its flight on the Lake Michigan somewhere between Sheboygan and Manitowoc, WI, the AMS said.
