A dark area, (DarkCool areas) appear at the surface the sun has changed about 11 anniversary year (11-year cycle) when the end comes the most. To cause to ion, remote communication is very good continuously in the one can see from the Sun spot number.Sunspot (Sunspot) is an area on the surface of the sun (photosphere) with temperature lower than the surrounding area. And the magnetic field of turbulence is very high.What is the intensity of the light is lower than the surrounding area. However, it still has a high temperature to 4000-4500 K. Compared with the surrounding normal temperatures around 5800 K.Welding was also the cause of the dark, phenomenon on the sun again. Such, coronal loop (Coronal loop), and the connection of the magnetic field. (Magnetic reconnection) also the explosion on a big sun (Solar flare).(Coronal Mass Ejection) also occur in the magnetic field around the dark.
