## Tools (as reported by the server, not verified)

- `noaa\_spaceweather\_get\_conditions`: 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\_alerts`: 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\_kp\_index`: 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\_wind`: 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
- `noaa\_spaceweather\_get\_solar\_activity`: 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\_aurora\_forecast`: 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
