A camera on the roof of the Atmospheric and Oceanic Sciences Building at the University of Wisconsin-Madison captured two images of the fireball at around 10:07 PM. The track was recorded by Doppler radar. Residents in Mifflin Township, Wisconsin, heard large explosions at the same time. The first stone recovered (7.4 g) hit the metal roof of a shed and was found the following day; it was identified as a meteorite at the University of Wisconsin-Madison.

More than 70 stones and fragments were recovered in the area within a few weeks after the fall.
