Get space weather data as one clean table: alerts, watches and warnings, the planetary Kp index (observed and 3-day forecast), R/S/G storm scales with 3-day probabilities, X-ray solar flares, sunspot regions with flare probabilities and the latest solar wind. Built on the public JSON services of the NOAA Space Weather Prediction Center. Useful for aurora alert apps, HF radio and GNSS operators, satellite and power-grid monitoring, dashboards and AI agents.
