Daily VHF SCADA Space Weather Briefing (September 7, 2025)
Daily Space Weather Briefing for SCADA (150–175 MHz)
1. NOAA Kp Index Forecast
- NOAA reports predicted geomagnetic storm activity at G1 (Kp ≈ 5) for today (September 7), with declining chances of G1-level tomorrow (40%) and lower the day after.

2. R‑Scale (Radio Blackouts) & S‑Scale (Radiation Storms)
- NOAA’s simple cartographic forecast shows no observed or forecasted R‑scale (radio blackout) or S‑scale (radiation storm) events for this period; all are marked “no data” or blank, indicating negligible risk.

3. GOES X‑Ray Spikes (Solar Flares)
- No current flare alerts (R1 or higher) are indicated in the forecast, implying the absence of significant M- or X-class solar flares at this time.

Overall VHF Link Condition: Guarded
Rationale:
- A G1 geomagnetic storm (Kp ≈ 5) today suggests potential minor ionospheric perturbations.
- No radio blackouts or radiation storms detected or forecast—both R‑ and S‑scale threats are absent.
- No significant X-ray flare activity, so additional shortwave interference is unlikely.
Summary Table
| Parameter | Status / Forecast | Impact on 150–175 MHz SCADA |
|---|---|---|
| Kp Index / Geomagnetic | G1 today (moderate risk), declining thereafter | Guarded – mild fading possible |
| R‑Scale (Blackouts) | No data / no events indicated | Guarded – negligible interference |
| S‑Scale (Radiation) | No data / no active or forecast events | Guarded – minimal risk |
| GOES X‑Ray (Flares) | No R‑scale flares currently | Guarded – stable ionospheric conditions |
| Overall Link Condition | — | Guarded – caution advised but operational |
