On October 24, 2011, a coronal mass ejection from the sun interacted with the Earth's magnetic field to produce a spectacular display of the aurora, or Northern Lights. The Northern Lights are usually only visible at high latitudes, but when the sun becomes more active the Northern Lights can be seen farther south. That was the case on October 24, where they were visible in central Indiana.
