noaa_spaceweather_get_conditionsread-only

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 the forecast. The quickest way to answer "is anything happening right now?" — use before deciding

noaa_spaceweather_get_alertsread-only

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 summaries, expired notices, and cancellations. max_age_hours controls how far back to look for candidates

noaa_spaceweather_get_kp_indexread-only

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 each G level at that level’s "minus" value: Kp 4.67 (5−) is G1, Kp 6.67 (7−) is G3 (aurora

noaa_spaceweather_get_solar_windread-only

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 record tagged with the reporting spacecraft and bounded to 200 records per series unless resolution

noaa_spaceweather_get_solar_activityread-only

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 per-region flare probabilities, and GOES integral proton flux at ≥10 MeV with NOAA S-scale. For o

noaa_spaceweather_get_aurora_forecastread-only

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 and G level needed for aurora at that geomagnetic latitude, the sun’s elevation there at the f
