"Potential Northern Lights Display Tonight After Severe Solar Storm"

A "severe" geomagnetic storm over the weekend was expected to bring the northern lights as far south as Alabama, but it may not be visible Monday night. Coronal mass ejections from the sun can trigger geomagnetic storms, impacting the visibility of the aurora. The storm reached "severe" G4 conditions, but only a few areas in the U.S. have a slim chance of seeing the northern lights Monday night. The University of Alaska Fairbanks Geophysical Institute forecasts high auroral activity reaching as far south as Oregon, Nebraska, and the East Coast, but local weather conditions and cloud cover may limit visibility.
