Mac,
 
Thanks for the clarification of the sun-spot cycle. We are in a low period  
of activity, no doubt. Certainly the astronauts would be at greater 
radiation  risk in their attempts to repair Hubble if the sun-spot cycle was more  
active.
 
Got a question about this topic. It was my impression that the "solar  
storms" strong enough to silence radio signals, GPS, and interfere with power  
grids were usually "C.M.E."s or cosmic mass ejections... events much larger 
in  scope and more violent than sun-spot activity. The question is about 
whether  the occurrence of C.M.E.s parallel the sun-spot activity cycle or 
whether  they occur either on their own schedule or at random. I am not aware 
that their  occurrence is predictable with any certainty...thoughts?
 
Thanks,
 
Alan Wentworth, WB9PWX
