Current Solar Conditions

What's important here is the K-Index, typically 0-9, and the SFI (Solar Flux Index), typically 50-300.

The lower the K, the quieter the atmosphere and the ham bands! However, the lower the SFI, the lower the MUF or Maximum Usable Frequency.

So, if for example, if you have a K of 1, nice and quiet, you might have a SFI of 50 which would mean that 20 meters might not be usable... The 'Calculated Conditions' section, above, summarizes this data and gives you a snapshot of what the band conditions should be when you are tuning around.
