Space Weather

Current space weather from NOAA SWPC public feeds.

Overview

Current space weather from NOAA SWPC public feeds. Returns the latest planetary K-index (3-hour geomagnetic activity), solar wind plasma (density / speed / temperature from ACE/DSCOVR at L1), GOES X-ray flux with NOAA flare class (A/B/C/M/X), and the current NOAA R (radio blackout) / S (solar radiation) / G (geomagnetic storm) scales plus a 24-hour forecast in 6-hour windows. All timestamps are ISO 8601 UTC. No parameters. Useful for aurora forecasting, HF-radio propagation, satellite-operations planning, and GPS-degradation alerts. Data is public domain (NOAA / US government work).
