Northern lights may be visible in Northern California amid severe geomagnetic storm

(FOX40.COM) — Sky watchers may be in for a treat as a severe geomagnetic storm is expected to trigger a colorful aurora in Northern California over the next few days. • Video Above: People all over California captured images of the northern lights

Aurora borealis, also known as northern lights, is caused by severe geomagnetic or solar storms. The last time the region experienced a solar storm strong enough to light up the night skies was in May of 2024. A measuring system called a “G rating” is used to identify a solar storm’s intensity. Storms are rated on a scale of 1 to 5, with 5 being the most severe.

, a current storm reached G4 levels Sunday afternoon and may last through Tuesday morning. Because of this, skylines across the U.S., including those in Northern California, have a high probability of soon being adorned with pink, purple, green, and blueish-colored lights.

. However, if the solar storm remains at G4 levels, Northern California and dozens of other states could get a glimpse of them.

The best way to view the northern lights is during the late night or early morning hours, and away from city lights. If visibility with the naked eye is difficult, experts recommend using a cell phone camera. Night mode on a cell device may also help enhance the view of the northern lights. In the past, the best time for viewing has been between 10 p.m. and 3 a.m.
