Current Solar Conditions
Solar Flux can vary between 50 and 300. Generally, the higher the Solar Flux, the higher the Maximum Usable Frequency and the better the HF conditions. For best HF conditions, the Solar Flux should remain above 150 for several days with a K Index of below 2.
The K Index is calculated every 3 hours. Generally, the lower the A Index reading, the better the HF conditions will be.
The A Index is calculated for a daily average of the K Index.
