According to NASA's Near-Earth Object Office website, data collected at the Marshall Space Center in Huntsville, Alabama, indicates that the fireball's parent body is not related to the Gamma Virgind meteor shower that occurred at the time the fireball entered the atmosphere.

Debris from Wednesday's fireball meteors fell over the town of Livingston, Wisconsin, in the area between the towns of Platteville and Avoca.

According to NASA's Near-Earth Object Office website, data collected at the Marshall Space Center in Huntsville, Alabama indicate that the fireball's parent body is not related to the Gamma Virgind meteor shower that occurred at the time the fireball entered the atmosphere. Instead, the small space rock most likely originated somewhere in the asteroid belt.

The head of the NEO office, Don Yeomans said that the fireball broke up high in the atmosphere, releasing energy equivalent to 20 tons of TNT. "Estimating the size of such a small asteroid allows us to measure the frequency of these events," Yeomans said. "Asteroids of this size are expected to enter the Earth's atmosphere once a month.

Michael Johnson, owner of the website Rocks From Space, says that according to Mike Farmer, a professional meteorite hunter, it appears to be an H chondrite meteorite.
