The northern lights, or aurora borealis, are an enchanting spectacle that can occasionally illuminate Colorado’s skies, despite the state’s southern location compared to typical viewing areas like Alaska and Scandinavia. These stunning displays occur when charged solar particles collide with Earth’s atmosphere, producing vibrant colors, primarily greens, but also pinks and purples. While rare in Colorado, enhanced geomagnetic storms can push the aurora further south, making sightings possible—especially during winter months when nights are longer and skies are often clearer. Ideal viewing spots include the northeast regions of the state, Pawnee National Grassland, and mountain communities like Crestone. To increase the chances of witnessing this natural marvel, enthusiasts should track solar activity using apps and tools, and prepare for photography with the right equipment. Although the aurora offers a captivating experience, successful sightings depend on specific conditions, including a KP index of 5 or higher, clear skies, and minimal light pollution.
