Often called the Northern and Southern Lights, these dazzling curtains of color occur high in the upper atmosphere, where charged particles from the solar wind collide with gases like oxygen and nitrogen. Oxygen collisions at higher altitudes, above 150 miles, produce the rare and ethereal red auroras.

Optimal Viewing Locations and Timing While auroras can occasionally appear at lower latitudes during intense solar storms, the best viewing opportunities consistently exist within regions known as the auroral ovals. The result is a dynamic show of pulsating curtains, rays, and coronas that can shift and evolve in real-time, making every aurora unique.
The same solar storms that create beautiful displays can pose significant risks to satellites, power grids, and radio communications. The periods surrounding the equinoxes in March and September often provide heightened aurora activity, and dark, clear nights during the long winters of these high-latitude locations offer the best chance for observation.

Closer to Earth, at around 60 to 150 miles, oxygen emits the most common and vivid green light. These oval-shaped zones encircle the magnetic poles, covering parts of Alaska, Canada, northern Scandinavia, Iceland, Greenland, and Antarctica.
