Tonight, the Northern Lights, or aurora borealis, are anticipated to illuminate the skies across 18 U.S. states due to heightened geomagnetic activity. This phenomenon occurs when charged solar particles collide with Earth's atmosphere, creating vibrant displays of light. The best viewing conditions are expected between 10 p.m. and 2 a.m. local time, particularly in dark areas away from city lights. States such as Montana, Minnesota, Wisconsin, and New York are among those where the aurora may be visible. The NOAA Space Weather Prediction Center indicates that geomagnetic conditions are favorable for sightings to extend further south than usual, offering a rare opportunity for millions. To optimize the viewing experience, experts recommend checking real-time aurora forecasts and selecting locations with clear northern horizons. For those interested in capturing the spectacle, using a tripod and adjusting camera settings can yield stunning photographs of the lights, which may appear brighter in images than to the naked eye.
