Will the Bay Area see Northern Lights this week?

OAKLAND, Calif. - The watch is on for another geomagnetic storm that could produce an aurora borealis, or northern lights across the United States late Friday night, according to the National Oceanic and Atmospheric Administration.

The Northern Lights can occur when a coronal mass ejection, or an eruption of solar material happens.

When that solar material arrives at Earth, it can result in a geomagnetic storm.

Northern California got lucky when the last geomagnetic storm hit. The northern lights were visible across some of the Bay Area, primarily where light pollution didn't have a huge impact.

Viewers shared photos they snapped of the incredible light show. But will the Bay Area see more lights during this week's eruption of solar material?

Northern lights or aurora borealis illuminate the night sky along a highway north of San Francisco in Middletown, California on May 11, 2024. The most powerful solar storm in more than two decades struck Earth, triggering spectacular celestial light shows from Tasmania to Britain -- and threatening possible disruptions to satellites and power grids as it persists into the weekend.

In short, it's not likely.

The aurora is expected to be visible in upper-Midwest states from New York to Idaho.
