The northern lights could illuminate the skies across up to 10 U.S. states on Friday night, according to data from the National Oceanic and Atmospheric Administration.
Where Will the Northern Lights Be Visible Friday Night?
Observers across the northern tier of the United States stand the best chance of catching a display. According to NOAA’s forecast map, visible auroral activity may reach northern Washington, the northern tip of Idaho, much of Montana, and Wyoming near the Montana border.
The visibility band also extends across North Dakota, northern South Dakota, northern Minnesota, the northern tip of Wisconsin, the Upper Peninsula of Michigan, and northern Michigan. Outside the contiguous United States, Alaska will maintain a much higher chance of seeing the aurora than the lower 48 states.
Understanding NOAA’s Kp Index Forecast
NOAA has issued a Kp index of five for Friday night. According to agency guidelines, a Kp index of five indicates a moderate geomagnetic storm that can produce northern lights views that are “quite pleasing” to look at for people positioned in the right geographic areas.
This viewing window is expected to be brief.
Pro Tips for Viewing and Photographing the Aurora
- Timing: Aim to watch between the hours of 10 p.m. and 2 a.m. local time.
- Location: Seek out high vantage points with little to no light pollution. Note that Friday features a full moon, which can impact visibility.
- Smartphone Settings: Avoid using your flash. Turn on night mode to capture clearer images.
- Camera Settings: Traditional camera users should utilize low apertures, wide-angle lenses, and sturdy tripods.
Solar Cycle Context and Long-Term Trends
Current auroral displays follow an exceptionally active solar period. Northern lights showings reached a 500-year high in 2024 as the sun reached the peak of its 11-year solar cycle, according to historical solar data.

Auroral activity has gradually tapered off since that peak and is expected to decrease further toward 2027.
Did you know? The Kp index is a scale used to characterize the magnitude of geomagnetic storms. Values range from zero (calm) to nine (intense storm), with higher numbers generally correlating with auroral visibility further away from Earth’s magnetic poles.
