A minor geomagnetic storm is expected to bring the northern lights to some of the northernmost U.S. states on Saturday night, according to a National Oceanic and Atmospheric Administration (NOAA) forecast. The auroral activity is predicted to be “quite pleasing to look at” with a Kp index of 3, which could reach a high point of 5.67.
Alaskans have the best chance of witnessing the northern lights, as almost the entire state falls within the NOAA’s forecasted range of the aurora’s view line. The northern parts of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, and Michigan may also be visible.
To increase visibility, experts recommend finding a high vantage point, avoiding light pollution, and traveling as far north as possible. The best time to see the lights is between 10 p.m. and 2 a.m. local time.
The northern lights have been active in American states this year due to solar activity exceeding scientists’ expectations. In 2024, some of the strongest solar storms in decades occurred, causing auroras with high Kp indices. The sun’s heightened activity is part of its 11-year cycle, known as the solar maximum, which will continue until 2026.
NOAA forecasts a minor geomagnetic storm on Sunday, but the northern lights are expected to weaken after Saturday night.
