Illinois was among nine states Sunday that reported a fireball streaking across the night sky, according to the American Meteor Society.
More than 270 reports came in from Illinois, Iowa, Minnesota, Indiana, Kansas, Nebraska, Ohio, Michigan and Wisconsin about 8:40 p.m.
“The estimated 3D trajectory computed from the witness reports shows an shallow entry angle, one that could be associated with an Earth grazing fireball,” the meteorological organization reported on its website. “But many witnesses reported a fragmentation – it could mean the meteoroid actually went through the Earth atmosphere.”
Another event was reported last January in which the fireball was accompanied by a “boom.”
