article_snippet.sent: The phenomenon is fairly common and the number of spots on the solar surface reflects with how active the sun is.
article_snippet.sent: the number of spots on the solar surface occur when a concentration of magnetic fields causes the surface temperature to reduce, making a specific section of the sun stand out from a specific section of the sun surroundings.
article_snippet.sent: Sunspots are also sometimes the source of eruptions on the sun, namely solar flares .
article_snippet.sent: The hot spots are also the source of eruptions on the sun, mainly solar flares and coronal mass ejections (CMEs), all of which are linked to magnetic fields.
article_snippet.sent: Sunspots should not be confused with coronal holes, regions of the corona - an aura of plasma around the sun - where the magnetic field reaches out into space rather than looping back down onto the surface.
article_snippet.sent: the sun spots are also the source of eruptions on the sun, mainly solar flares and coronal mass ejections (CMEs), all of which are linked to magnetic fields (a picture of a coronal mass ejection taken by Mr Ewen, pictured)
