The aurora borealis (northern lights) and aurora australis (southern lights) are natural light displays caused by charged particles from the sun colliding with Earth's atmosphere.

Current Geomagnetic Activity (Kp Index)

📊 Kp-Index Explained

The Kp index measures geomagnetic activity on a scale of 0-9. Higher values indicate stronger aurora displays at lower latitudes.

Kp 0-3: Quiet
Kp 4: Unsettled
Kp 5: Active
Kp 6-7: Storm
Kp 8-9: Severe Storm

Solar Wind Conditions

🧲 Bz Explained 🌞 Solar Wind Explained

Better aurora viewing occurs when: Solar wind speed is high (>400 km/s) and the magnetic field Bz component is strongly negative (< -5 nT). These conditions allow solar particles to more effectively interact with Earth's magnetosphere.
