`kp_index`

Pack: noaa-swpc · Endpoint: https://gateway.pipeworx.io/noaa-swpc/mcp

NOAA planetary K-index — global geomagnetic activity 0–9, the standard aurora/storm indicator (Kp≥5 is a geomagnetic storm). Windows: now (single freshest estimated value) | 1-day (3-hourly observed, feed carries about a week) | 7-day (observed plus 3-day forecast; each row flags which) | 1-minute (1-minute estimated, last ~6 hours). SWPC retired its 30-day archive, so no month-long Kp history is available from this source.
