Although I find the A and K mostly useless, I do see a clear trend
that follows the Aurora level for near-the-pole paths. I use a system
that automatically e-mails me the solar conditions in a level that
isn't too difficult for my non-ionospheric mind to absorb.
Here is a sample of the information:
SFI:232 | A:4 | K:1 down from 2 at 1800 on 14
November.
SAF: moderate, GMF: quiet to unsettled
Aurora Level: 4
Solar Wind: 297.3 km/s at 3.5 protons/cm3
