Sun extra credit

Extra Credit
The sun goes through cycles ever 11 years. Dark spots start appearing on the suns surface. When there are no sunspots that means that there are no solar flares. And when there are no sunspots then it disturbs radio and satellite communications.  Also it disturbs the climate.  The last cycle was supposed to be in 2008, but it did not appear, and that means there is no new cycle.  Which is a good thing for operators of communication satellites, because the sunspots haven't interrupted their communications
