> hi reflectees !
> As we all know, the effects of the solar wind are strongly determining
> 160m propagation. It seems that solely watching A and K indexes plus the
> SFI is not helping much in propagation predictions, at least not for
> 160. We all tried that and failed in it. Now is the critical factor
> whether the polarity of the arriving solar wind, developing the
> interplanetary mag field , fits the earth mag field or not. becuase if
> it does, the influence is by far greater than without it.
> Question is, where do i find that info ?? I think this might stir up
> some geophysicist - hopefully. Surely the information derived that way
> is not as easy to grasp as a simple number, but it may be the only way
> to further the cause.
