Tip: Sustained Bz < 0 (southward) + elevated Kp often means aurora/VHF fun — and HF can get rough.

Live Panels (NOAA SWPC)
Planetary K Index
Kp
NOAA Planetary K Index plot

Higher Kp = more geomagnetic disturbance (aurora chances go up, HF can get weird).

GOES X-ray Flux
Flares
NOAA GOES X-ray flux plot

Sudden spikes can cause HF fadeouts (R-scale radio blackouts).

Solar Wind (Mag + Plasma)
IMF

Look for sustained southward Bz (often a “storming / aurora” ingredient).

Aurora Oval
OVATION
NOAA Ovation auroral oval (North)

Quick scan: is the oval pushed south enough to matter in the West?

Coronal holes and active regions can hint at incoming wind streams and flare potential.

Complex sunspot magnetic regions correlate with stronger flare risk (watch X-ray).

What to Watch

HF / VHF Quick Guide

  • HF suddenly dead? Check X-ray plot (flare blackout) + R-scale.
  • Aurora/VHF scatter? Check Kp + G-scale + aurora oval.
  • Conditions about to change? Watch Bt/Bz and wind speed trends.
  • HF “better lately”? Solar flux (F10.7) often tracks improved HF potential.
