Sunspot on the setting Sun. The single sunspot is seen towards the centre of the solar disc. Sunspots are found in the solar atmosphere and appear to be darker than the surrounding regions due to their lower temperature. They are found in association with regions of extremely high magnetic fields. Sunspots may cover an area of billions of square kilometres, large enough to be seen with the naked eye.
