Hi Paul & all

Yeah.. I've had similar observations & it's one of the hardest things to 
predict/monitor.. I've had great reception during major storming.. I suppose it 
depends on where you are & what effect the storm has had on the circuits..

I'm not sure if too much scientific research has ever been done in this area.

As far as knowing what conditions are like.. the bottom line is to just turn 
the set on & see.. I've never been one to pay too much attention to the 
reports..

However.. getting back to what I first mentioned.. It would be mighty 
interesting to know on average what solar conditions are like when we have good 
East/West & Nth/Sth paths open with above average signals.

Yup.. It only came to my attention over the christmas break when we had those 
two or three days of low A Index's.. I think zero for two days.

I couldn't even hear our old mate KCWW on 1580.

Yeah but why?? Would be interesting to know huh?
