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 northern lights display should continue well into the weekend, possibly reaching down into the middle parts of the country.

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 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. states, according to the National Oceanic and Atmospheric Administration.

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.

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

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