Sunspots increase and decrease through an average cycle of 11 years. The solar cycle has been plotted dating back to the mid 1700s. Dating back to 1749, we have experienced 22 full solar cycles where the number of sunspots have gone from a minimum, to a maximum and back to the next minimum, through these approximate 11 year cycles. We are now well into the 23rd cycle and the number of sunspots in this cycle reached a peak in May of 2000. The jury is still out on this question.
