Jun 15 2009 (IPS) - Areas on the surface of the sun, which in periods are a little colder than the rest of the surface and appear as dark spots. Sunspots are formed by powerful magnetic fields in the sun, and their number indicates the sun’s activity. The sun’s magnetic fields influence the amount of so-called cosmic radiation that can reach the earth’s atmosphere.
