A coronal mass ejection (CME) hit earth at 14:00 EDT yesterday, setting up a fantastic Northern Lights show later that night.
The Aurora Borealis is a rare sight over the contiguous United States, but thanks to a solar storm, people from Michigan to Alabama could see swaths of pink and green in the night sky.
In a CME, the impact compresses Earth’s magnetic field, directly exposing geosynchronous satellites to solar wind plasma and sparking an intense geomagnetic storm, according to SpaceWeather.com.
