The Muscoda Police Department caught video of the fireball on a squad dash cam facing east:
That wasn't the only sighting. UW-Madison's Atmospheric and Oceanic Sciences school also caught the spectacular display from one of their rooftop cameras.
A professor from the school told TODAY'S TMJ4 fireballs like the one spotted in the sky Monday night are pretty common, although it's not common that they're actually visible.
According to the professor, the fireball could have been a meteor, a small piece of rock, or even space junk burning up in the atmosphere.
Comment: The American Meteor Society (AMS) received 160 reports yesterday about a fireball seen over Wisconsin and neighbouring states. On January 30th 2016 there were 880 reports of meteor fireball sightings over Northeast US and Canada. See also: Fireball seen over Northeast US
