Why Aurora Happens

1. Solar Wind

Solar flares and CMEs send charged particles toward Earth at up to 800 km/s.

2. Magnetosphere

Earth's magnetic field deflects most particles, funneling them toward the poles.

3. Atmospheric Collision

Particles collide with atmospheric gases, exciting electrons to higher energy levels.

4. Light Emission

Electrons fall back, releasing energy as photons — the colorful aurora we see.

🌌 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.
