Current GOES X-ray flux class
Solar wind speed and magnetic field strength indicate current space weather activity. Elevated or storm-level readings can disrupt satellites, GPS accuracy, and power grids. This is a planetary-scale signal, not specific to this location — typical quiet conditions run under 400 km/s wind speed and under 5 nT magnetic field.
