What This Means

Even with strong solar activity, cloud cover or moonlight can make aurora difficult to see. AuroraVision combines solar wind data, geomagnetic storms and local weather conditions to estimate your actual visibility.

Why Aurora Happens

From the Sun to the sky — the full process

Solar wind: charged particles streaming from the Sun toward Earth at 400–800 km/s

Magnetosphere: Earth's magnetic field guiding solar particles toward the auroral zones at the poles

Atmospheric collision: charged particles colliding with oxygen and nitrogen molecules at 100 to 300 km altitude

Light emission: aurora borealis displaying green, red, blue and purple colours from excited oxygen and nitrogen
