Northern lights, storm and California
Digest more
The Northern Lights could return to Northern California on Monday. A coronal mass ejection, known as a CME, arrived from the sun earlier than expected on Monday and was creating a strong geomagnetic storm in Earth's magnetic field, which has the potential to impact power grids, space operations and radio and satellite communications.
A 'severe' geomagnetic storm is set to brighten up the skies for many U.S. residents tonight, and will likely be visible much farther south than usual.
