[Elecraft] OT -- Sunspot Cycle 25

I have very little doubt that the next sunspot cycle will be pretty 
weak.  The long term trend has been pretty obvious in general. However, 
it seems erroneous that they would predict a delay in the start when the 
first (albeit weak) sunspot of Cycle 25 (opposite polarity) has just 
recently been spotted.

And I've seen no scientific analysis at all that says there won't be 
some sort of maximum at all.  NOAA's Space Weather Prediction Center 
even expects a solar maximum roughly the same as for Cycle 24.

Who knows what the actual story will be (I certainly don't), but I'm 
going to place a CQ article fairly far down my list of credible sources.

To quote from the reported studies,  “ . . . the start of Cycle 25 could be delayed to 2021 or 2022 and will be very weak, if it even happens at all . . . .  this (Cycle 24) could be the last solar maximum we’ll see for a few decades . . . .”  Guess I’d better gear up for FT8.
