According to Thursday reports from National Weather Service offices across the Midwest, a huge ‘green’ meteoroid ignited over Wisconsin, Iowa, Illinois, and Missouri about 10:15 p. m., local time, on Wednesday night.
Though there have thus far been no reports of injuries, authorities say that large meteor fleetingly turned night into day across the Midwestern sky – streaking across southwestern Wisconsin, northern Iowa, and central Missouri -, and even rattled houses and caused a shaking of trees as well as the ground.
As per Ashley Sears, a meteorologist with the National Weather Service office at Milwaukee, radar information hints that the meteor landed in the southwest corner of Wisconsin, either Grant or Lafayette counties. However, there have been no official reports of anyone having seen a meteorite or a crater in either of these two counties.
On the basis if a video, astronomer Mark Hammergren, who missed the sky show himself, said that the fireball probably was up to six feet wide and weighed approximately one thousand pounds or more. The greenish color of the meteor resulted from a combination of the heating of oxygen around it and the mix of minerals ignited as it entered the Earth’s atmosphere.
Based on the size of the halo, James Lattis, the director of the University of Wisconsin Space Place in Madison, said that meteor was merely the size of a softball or basketball.
