Sunspot Cycle Progression

The Current Sunspot Cycle

The current solar cycle made a bottom in late 2009 and early 2010. It has been higher since that low, but notice that sunspot counts were significantly lower throughout all of 2012 than solar physicists predicted. It remains to be seen whether counts wil rise up near predicted values this year before trending lower or they will simply trend down from where they are now.
