The effects of a coronal mass ejection—a bubble of plasma that bursts from the sun’s surface—will likely impact Earth’s magnetic field on Saturday, bringing the northern lights to several northern U.S.

The agency expects a minor or greater geomagnetic storm—a disturbance of Earth’s magnetic field—on Saturday, which increases the likelihood of northern lights displays being visible to more people, as the effects of a recent coronal mass ejection reach Earth, according to NOAA’s three-day forecast.

The colorful northern lights may reveal themselves to a wide swath of Americans Friday night due to an impending solar storm forecast to reach Earth.

The National Weather Service has issued a winter weather advisory for the Sacramento area until Sunday at 4 p.m., with wind gusts up to 55 mph and a 70% chance of rain, and the Placerville area expecting 4 to six inches of snow.

A coronal mass ejection earlier this week may pull the northern lights to more northern U.S. states, forecasters said.

Sky gazers in several U.S. states could get a colorful glimpse of the northern lights as we enter the weekend, thanks to a recent geomagnetic storm.

Millions of Americans could witness the stunning solar light show in different states over the weekend as a higher-strength geomagnetic storm passes overhead.
