  5. New ‘Sun clock’ reveals that solar activity turns off and on with surprising precision

    Solar scientists have taken a mathematical technique used by Earth scientists to analyze cyclic phenomena, such as the ebb and flow of ocean tides, and applied it to the confounding irregularity of cycles on the Sun. The result is an elegant “Sun clock” that shows that solar activity starts and stops on a much more precise schedule than could be discerned when looking at observations of the Sun in the traditional way – plotted linearly over time.
