The aurora borealis lit up the night sky across wide swaths of North America Monday night, and thanks to YouTube, the Internet was quickly flooded with videos of the phenomenon. While the lights in the night sky are rarely visible through most of the 48 continental states, this time they were visible as far south as Arkansas.

According to SpaceWeather.com a coronal mass ejection (CME) from the sun arrived around 2 PM Eastern Time, which compressed the Earth's magnetic field and "sparked an intense geomagnetic storm." That means all those pretty lights came spilling across the Canadian border into the United States.
The effects led many to call in to local news stations or take pictures and video and put them online. Check out a few of the videos below, and for more information about the Aurora, check Wikipedia because, honestly, they're just smarter than us.
