The aurora borealis, also known as the northern lights, has been visible in parts of North America, typically in regions at high latitudes such as Alaska and northern Canada. The natural light display occurs when conditions in the upper atmosphere allow charged solar particles to interact with Earth’s magnetic field, producing glowing curtains of light across the night sky. Activity tends to increase around the equinoxes in March and September and during periods of heightened solar cycle activity. Locations such as Fairbanks in Alaska and Yellowknife in Canada’s Northwest Territories are among the most reliable places for viewing.
Viewing is most consistent on clear, dark nights, generally between late August and early April in the Northern Hemisphere. This window reflects seasonal darkness and atmospheric conditions that improve visibility of the aurora. Peak opportunities often align with equinox periods in March and September and phases of stronger solar activity within the solar cycle, which can expand how far south the lights are seen.
