The impact can be amazing - the HF bands can go dead in an instant making you wonder your radio broke. fiik golfWebThe X-ray flux level is also affected by the overall solar activity level due to sunspots, which can be see in the baseline (non flare) levels. Higher values can result in better propagation on the higher frequency bands.
