Hi Jay yes thanks, and that it perks up a bit with a low level coronal =
hole event around Kp=3D4. I have just found a useful source of reading =
matter so I have invested this month's beer money :-))  Hopefully I will =
have a more "scientific" explanation when I have absorbed that. Even is =
suffering from too much blood in my alcohol stream by then.

  Interesting explanation - always appreciate your thoughts on the =
subject! Have certainly witnessed the 'quiet condition signal drop off' =
for years on the T/A path.
