Sunspots usually occur in pairs or groups of opposite magnetic polarity that rotate with the surface of the Sun. They are the footprints of magnetic loops pushing through the surface and holding plasma below.  Manifesting intense magnetic activity, sunspots host secondary phenomena such as coronal loops and reconnection events.
