Gives a plain-English 'is the radio open' read on HF band conditions right now, per band (160m/80m/40m/20m/17m/15m/12m/10m), derived from NOAA/SWPC's current 10.7cm Solar Flux Index (SFI), planetary K-index, and planetary A-index using the standard ham-radio SFI/K/A heuristic. Use this when asked things like 'are bands open', 'how's propagation', 'what band should I use', or 'is 10m open today' — it returns both a concise summary and the raw SFI/K/A numbers it was derived from. Day/night bias in the per-band notes is based on this server's local time, not the asker's location, since this tool takes no location input — treat that part as approximate for other locations/timezones. This is a coarse heuristic, not a substitute for real MUF/VOACAP modeling of a specific path.

Returns the latest raw space-weather indices used for HF propagation assessment: the 10.7cm Solar Flux Index (SFI, in sfu), the planetary K-index (Kp), and the planetary A-index (running 24h average), each with its NOAA observation timestamp (UTC). Use this when asked for 'the solar flux number', 'current Kp', 'today's A-index', or when you need the raw numbers rather than a band-by-band interpretation (for that, use get_band_conditions instead).

Returns NOAA/SWPC's 3-day-ahead planetary K-index (Kp) forecast table, one row per 3-hour period, each with its UTC time, predicted Kp, and NOAA G-scale (if a geomagnetic storm threshold is predicted to be reached). Use this when asked about 'upcoming geomagnetic activity', 'will there be a storm this week', or 'Kp forecast for the next few days' — as opposed to get_solar_indices, which is current conditions only.

Returns the N most recent active NOAA/SWPC space-weather alerts, watches, and warnings (e.g. geomagnetic K-index warnings, radio blackout/Type II radio emission alerts, proton flux alerts), most recent first. Each result includes the alert type code, UTC issue time, and a short plain-English extract of the bulletin (not the full raw text). Use this when asked 'any space weather warnings right now', 'is there a solar storm alert', or 'what's the latest SWPC bulletin'.

Returns the current real-time solar wind reading at L1: interplanetary magnetic field strength (Bt) and its north-south GSM component (Bz, in nT — a sustained strongly negative/southward Bz is what actually couples solar wind energy into the magnetosphere and precedes geomagnetic storms), plus proton speed (km/s), density (protons/cm^3), and temperature (K). Use this when asked 'what's the solar wind doing', 'is Bz south', or when a get_band_conditions/get_kindex_forecast answer needs the upstream driver data explaining why Kp is doing what it's doing — solar wind changes typically precede a Kp response by 30-60 minutes.

Returns the latest GOES X-ray flux in both channels (long, 0.1-0.8nm, and short, 0.05-0.4nm, in W/m^2) plus NOAA's own current solar flare classification (e.g. 'C1.5', 'M2.0', 'X1.1' — the standard A/B/C/M/X logarithmic scale, computed by NOAA from the long channel, not re-derived here) and details of the most recent classified flare event (begin/peak/end time and class). X-ray flares cause sudden ionospheric disturbances (SID) — sudden HF absorption/blackout on the sunlit side, distinct from and faster-onset than geomagnetic-storm degradation. Use this when asked 'any solar flares', 'what class is the current flare', or 'is there an X-ray event happening'.
