Aurora Observatory
This page provides a real-time view of space weather conditions and how they influence aurora visibility. By combining solar wind data, magnetic field behaviour, and geomagnetic activity, you can quickly assess whether aurora may be visible from your location.
Solar Wind
A stream of charged particles from the Sun. Faster wind and shock arrivals can trigger geomagnetic disturbances.

IMF & Bz Magnetic Field
A southward Bz allows energy into Earth's magnetosphere — the primary trigger for aurora activity.

Density & Energy Flux
Higher pressure compresses Earth's magnetic field and enhances aurora intensity.

KP Index
A global geomagnetic index (0–9) derived from a worldwide network of magnetometer stations measuring disturbances in Earth's magnetic field.

Coronal Mass Ejections (CMEs)
Large eruptions from the Sun that drive major geomagnetic storms and strong aurora displays.

Coronal Holes
Regions emitting high-speed solar wind streams, often causing recurring aurora activity.

Auroral Oval
A ring around Earth's poles where aurora forms — expanding toward lower latitudes during strong activity.

Observer Latitude
Your location matters — stronger activity pushes aurora further south.
