On April 16, 2010, Noriko Kita, director of the Ion Microprobe Laboratory and a meteorite expert at the University of Wisconsin-Madison, removes a piece of rock believed to be from the April 14 meteor that showered the night sky over Southwestern Wisconsin from a scanning electron microscope following analysis. The fragment was found by a Wisconsin farmer and brought to the university for analysis.

Analyzed in a University of Wisconsin-Madison geoscience lab on April 16, 2010, a piece of rock measuring about 2 inches by 3/4 of an inch and weighing 7.5 grams is believed to be from the April 14 meteor that showered the night sky over Southwestern Wisconsin. Pictured here is the outer layer, which has a thin layer of smooth brown/black "fusion crust" on the surface that forms when the meteor heats up passing from cold space through the earth's atmosphere. The fragment was found by a Wisconsin farmer and brought to the university for analysis.
