Aren't we fortunate to have had radio invented at this point of
relatively high sunspot activity rather than at a "Maunder Minimum" type
period? Not much hope for 10 meters if we had that going on now.
Decades of no sunspots at all.....eeeek!
Even the low end prediction of 45 sunspots would be better than a true
minimum.
Guy, the plots that go all the way back to Galileo show that there are
large variations in both the upward and downward trends--in the sequence
of cycle 11 thru cycle 16, what if cycle 13 is the oddball? But then
are these really large variations in a system as big as the sun?
O'course, that curve fitting exercise only reinforces the opinion that
the next cycle should be lower, or trending down. (That's my own
guestimate too). But what if the current group of higher activity
cycles is going to last a few cycles longer than historical sunspot
trends predict? I'm betting that the data is too narrow to show the
longer term(millennial) cosmic scale trends that may well exist in a
system so large and complex as the variability of a star. It may take a
few thousand years of observations to see what's really happening.
Mayhaps time will bring fullness. Perhaps our distant unborn
descendants will be able to be certain. Right now, I'm pretty certain
that no one is certain.....
For now, I'm going to hope the guys pushing the 'conveyer belt' theory
are right about predicting 'short term'(decades) behavior, that you and
I are wrong about following the 'short term'(centuries) curves --and
that we are all so fortunate as to be in good health to see the short
term result over the next ten years. :)
Woo hoo!

careful with that SUV, Eugene.......or maybe not.
