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

Planetary K Index
Kp
Higher Kp = more geomagnetic disturbance (aurora chances go up, HF can get weird).
GOES X-ray Flux
Flares
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
Quick scan: is the oval pushed south enough to matter in the West?
NASA Sun Context (SDO)
SDO AIA 193Å
NASA
Coronal holes and active regions can hint at incoming wind streams and flare potential.
SDO HMI Magnetogram
NASA
Complex sunspot magnetic regions correlate with stronger flare risk (watch X-ray).
