@moduledoc """
|

Polls NOAA SWPC's free public JSON services for the three space-weather
|
|
products we use for HF / Es scoring:
|
|
|
|
- Planetary K-index (1-min cadence) — geomagnetic disturbance level
|
|
- 10.7 cm solar flux (hourly) — SSN proxy for HF MUF prediction
|
|
- GOES X-ray flux (1-min, 0.1-0.8nm band) — short-wave fade from flares
|
|
|
|
Runs on a 5-minute cron. SWPC publishes Kp and X-ray at 1-min cadence;
|
|
5 minutes strikes a balance between freshness and request volume. Each
|
|
fetch is independent: a failure in one product doesn't block the others.
