Northern U.S. states prepare for potential northern lights viewing tonight

On April 10, 2025, the northern lights are expected to be visible in several northern U.S. states, despite the presence of a 97%-lit waxing gibbous moon. The forecast from the National Oceanic and Atmospheric Administration (NOAA) indicates a Kp index of four on a scale of nine for auroral activity that night. This suggests that, given the right conditions, viewers could witness auroras, although bright moonlight may hinder the visibility of the phenomenon. Regions most likely to experience these lights include northern Washington, northern Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Maine, and along the U.S.-Canada border in Vermont and New Hampshire. The auroral oval is typically centered over polar regions, but factors such as solar activity can cause it to extend further south, providing opportunities for sightings even in states that normally may not experience them. The expectations for auroras coincide with the impending full pink moon, which will rise in the evening, offering a contrasting celestial event. Moonlight can significantly affect astronomical observations, making fainter events like auroras harder to spot. Local residents along with astronomy enthusiasts are gearing up for what could be a visually stunning display if conditions align correctly. While the northern lights can be seen most frequently from September through March in polar areas, April and May can still see activity if the auroral oval expands, especially in areas where there is still some darkness. This potential auroral display comes as excitement grows around celestial events, especially among those who actively partake in stargazing and similar activities. As the night sky unfolds, observers will be watching closely, hoping for a chance to view the magical lights dancing across the horizon, all while basking in the glow of the full moon above.
