Today, there are two sunspots in the sun’s southern hemisphere. Their magnetic polarity reveals something interesting: They come from different solar cycles. Take a look at this magnetic map of the sun’s surface (with sunspots inset) from NASA’s Solar Dynamics Observatory:
One sunspot (AR2760) belongs to old Solar Cycle 24, while the other (AR2761) belongs to new Solar Cycle 25. We know this because of Hale’s polarity law. AR2760 is +/- while AR2761 is -/+, reversed signs that mark them as belonging to different cycles
