Per WWV, the solar flux is at 91. What, if any, affect does this have on propagation in HF or other frequency bands....and of course 160 meters. I have seen these geophysical numbers often, but never really understood what they meant. The flux has been running in the high 60s/low 70s until a few weeks ago when I saw it in the 80s.
