Solar Flares & Prominences

Sunspots are areas of lower temperature but high activity on the sun. These are caused by the looping and shearing of the magnetic field lines due to the sun's differential rotational speeds (i.e.: equator rotates faster than poles). Many times, flares and prominences (loop-like structures) are associated with these sunspots.
