StormSentinel is an independent, ground-based geomagnetic monitoring station. It continuously records magnetic field variations and correlates them with solar activity, providing real-time detection of solar flares and geomagnetic disturbances.
The Activity Index measures the degree of correlated magnetic variation between independent instruments. Values above 4.5 indicate a confirmed geomagnetic response. Values above 8.0 trigger an ALERT status.
