GET /spaceweather/kp
Get recent planetary K-index (Kp) values from NOAA SWPC, the primary indicator of geomagnetic storm activity. The Kp index ranges from 0 (quiet) to 9 (extreme storm). Values of 5+ indicate geomagnetic storms visible as aurora at lower latitudes. Returns a time series of recent Kp readings. Critical for aurora prediction apps, satellite drag calculations, GPS accuracy monitoring, and space weather dashboards.
