[CQ-Contest] Sunspots

[ALAN BRAUN]

The way they do the sunspot calculation,  there is no way to have a number between 0 and 10. It will be either 0 or 11, then go up from there. Look at some of the old sunspot number archives & you'll see this. Flux is a better way to get a linear relationship of activity at the low end. The lowest possible flux number is 66.
