A strong geomagnetic storm is expected to send the glowing lights of the Aurora Borealis streaking across the skies over 17 states in the U.S. later this week, according to a forecast from the Geophysical Institute of the University of Alaska. The Aurora Borealis, also referred to as the Northern Lights, is caused when electrons from the sun enter Earth's upper atmosphere. According to the National Oceanic and Atmospheric Association (NOAA), the Planetary K-index (Kp) is a scale used to define the magnitude of geomagnetic storms on a scale of 1-9.
