Northern lights expected to illuminate parts of the U.S. tonight

On March 31, 2025, forecasts from the National Oceanic and Atmospheric Administration (NOAA) indicated that parts of the northern United States may witness the stunning natural phenomenon known as the northern lights, or aurora borealis. This potential display is attributed to a predicted Kp index of three, which suggests mild auroral activity could be visible from certain locations if conditions are favorable. The viewing line, which tracks where the northern lights can be seen, is expected to stretch down to the border between North Dakota and South Dakota. However, the conditions for viewing are more favorable the farther north observers are located. Areas identified as having a low likelihood of seeing the northern lights include the northeastern tip of Washington, northern Idaho, northern Montana, North Dakota, northern Minnesota, northern Wisconsin, Michigan’s upper peninsula, and the northern tip of Maine. In contrast, regions in Canada and Alaska are expected to experience even better visibility, enhancing opportunities for residents and visitors there to see this captivating natural light display. For those seeking to catch sight of the lights, the ideal viewing times are between 10 p.m. and 2 a.m. Finding a high vantage point with clear skies and minimal light pollution will significantly increase the chances of experiencing the phenomenon. Photographers are encouraged to employ night mode on their smartphones and use tripods to capture the lights effectively. Additionally, utilizing wide-angle lenses, wide apertures, and high ISO values will help enhance the images. Looking back, researchers indicate that recent solar activity from last year has led to increased occurrences of the northern lights. The sun reached a phase known as 'solar maximum,' resulting in heightened solar events like flares and coronal mass ejections. Accordingly, NASA suggests that this elevated activity could last well into the next year, offering more opportunities for skywatchers to experience the aurora borealis throughout 2025. However, it is important to note that the following night, April 1, 2025, will likely present drastically reduced chances for northern lights viewing, with a Kp index downgrade to two and the viewing line expected to be mostly outside the contiguous United States.
