Solar activity undulates on an 11 year cycle. At the "solar maximum" there are more solar flares, more sunspots, more sun quakes, more of everything that solar physicists love to study. But the solar cycle is not just for academics -- it affects everyday life on Earth, sometimes in unexpected ways. Northern lights have inspired art and poetry. A new science was born earlier this century thanks to the solar minimum. There's no evidence, but some people claim that even the length of mini-skirts and the performance of stocks are affected by sunspots....Courtesy National Oceanic and Atmospheric Administration

What is interesting here is that Sunspots activities were predicted to increase again at about 2007 but instead its has been on a decline as shown by the red markings.
Interestingly it coincide with a scientific study that shows Sunspots is going on a hibernation.
