Storm Preparedness Checklists
Practical, role-specific checklists for when space weather strikes.
- Monitor NOAA SWPC for X-class flare alerts — HF blackouts can occur within 8 minutes
- Switch to lower HF bands (80m/40m) during geomagnetic storms — higher bands may close
- Keep a backup NVIS antenna for disturbed conditions
- Log propagation conditions before and after storms for QSL records
- Subscribe to Flarient Premium for instant G2+ storm notifications
- During A-index > 50, expect heavy absorption on polar routes
- Test emergency frequencies during quiet periods so you know your baseline
