Multiple sources have reported seeing some sort of fireball or meteor over the skies of southern Wisconsin Monday evening.

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.
