• noaa_spaceweather_get_alerts ~564 tokens
  Active SWPC alerts, watches, and warnings — parsed into structured records with product type, NOAA scale and level, issue time, serial number, validity window, and plain text. Covers geomagnetic storms, radio blackouts, and radiation storms. With active_only=false, also returns informational summari
• noaa_spaceweather_get_aurora_forecast ~378 tokens
  OVATION model aurora forecast for the next ~30–60 min: global grid of aurora probability percentages by latitude/longitude (1° resolution). With optional coordinates, returns the local aurora probability at the nearest grid point, the geomagnetic latitude those coordinates convert to, the minimum Kp
• noaa_spaceweather_get_conditions ~294 tokens
  Current space-weather snapshot: NOAA R/S/G storm scales (the previous UTC day, today, and the 3-day forecast), latest Kp index with its G-scale equivalent and aurora-visibility latitude, and a plain-language status summary. Optionally includes the SWPC forecast discussion explaining what is driving
• noaa_spaceweather_get_kp_index ~285 tokens
  Planetary K-index (0–9 geomagnetic activity scale) — recent observed 3-hour values with their NOAA G-scale equivalents and aurora-latitude guidance, plus the 3-day Kp forecast series. Kp is the primary driver of aurora visibility and geomagnetic storm severity. SWPC reports Kp in thirds and starts e
• noaa_spaceweather_get_solar_activity ~412 tokens
  Solar flare and radiation storm picture: discrete flare events from the past week with peak class and R-scale level, recent GOES X-ray flux with flare-class labels (A/B/C/M/X) and class magnitude, the daily F10.7 cm solar radio flux, 3-day flare-class probabilities (C/M/X), active solar regions with
• noaa_spaceweather_get_solar_wind ~709 tokens
  Real-time solar wind measurements from the active spacecraft at L1: proton speed (km/s), density (n/cm³), temperature (K), and the critical Bz component (southward Bz = negative = storm driver). Returns the recent plasma and magnetic field time series within the requested window, oldest first, each
