Understanding Aurora Conditions
KP Index 5+: High geomagnetic activity. Northern lights visible at lower latitudes including northern US states.
Bz Field < -3nT: Favorable magnetic field orientation for aurora activity. Negative Bz enhances geomagnetic storms.
Solar Wind 500+ km/s: Fast solar wind streams interact with Earth's magnetosphere to create aurora displays.
Best Viewing: Dark skies away from city lights, looking north during peak activity hours.
