Band history
Band Condition Time Machine
Rewind recent solar history and inspect how 10m would have scored at your location. This is a heuristic reconstruction from stored SFI, SSN, and K-index snapshots.
How to use these charts
For high bands (especially 10m), look for high SFI/SSN with low Kp. If Kp rises, expect polar paths to degrade first; shift strategy toward lower bands (20m/40m/80m) and check grayline windows.
For flare-related blackouts, watch X-ray class spikes—stronger events can temporarily wipe out HF on the sunlit side. When conditions recover, openings often return quickly.
