NOAA Forecasts Aurora Borealis Visible in 9 US States Wednesday Night with Kp Index 4

Topline

Up to nine states in the northern U.S. may be able to see the northern lights Wednesday night, according to the National Oceanic and Atmospheric Administration (NOAA), which forecasts mild auroral activity and minor geomagnetic storm impacts.

Key Facts

• The aurora may be "quite pleasing" to look at for observers in the right areas, according to NOAA, which forecast a Kp index of four on its scale of nine.
• NOAA has also forecast a minor geomagnetic storm, which can improve northern lights visibility at higher latitudes.
• Auroral activity is forecast to increase tomorrow, according to NOAA, which forecasts a Kp index of five for Thursday night.

Where Will the Northern Lights Be Visible?

Areas within Wednesday’s northern lights forecast include:

• Northeastern Washington
• The northern tip of Idaho
• Northern Montana
• North Dakota
• The northernmost stretches of South Dakota
• Northern Minnesota
• Northern Wisconsin
• The Upper Peninsula of Michigan

Chances to see the northern lights are even higher in Alaska and significantly increase the farther inland observers are in the state.

What's the Best Way to See the Northern Lights?

High vantage points and places with little to no light pollution can improve chances of seeing the northern lights, which are usually best viewed between 10 p.m. and 2 a.m.

What's the Best Way to Photograph the Northern Lights?

Taking photos with low apertures and wide-angle lenses, if applicable, can help with photos of the aurora, as can tripods and night mode. Smartphone users should avoid using flash.

Key Background

The northern lights reached a 500-year high in 2024 when the sun reached the peak of its 11-year solar cycle. Scientists expect auroral activity to taper off significantly by 2027 as the sun gets farther from the peak.
