What am I looking at?
- SFI / SSN — solar flux & sunspot number. Higher generally means better HF propagation, especially on the higher bands (10–15m).
- A / K index — geomagnetic activity. Low is good; high (K ≥ 4) means disturbed conditions and possible auroral absorption.
- Band conditions — N0NBH's day/night HF estimates. Green = good, amber = fair, red = poor.
- Kp & solar wind — geomagnetic storm level and incoming solar wind. Watch Bz going strongly negative for aurora & disruption.
- Live activations — operators currently on the air for POTA & SOTA. Great targets to chase.
