Large sunspots as the sunspot group NOAA 11944 are of particular interest because they show very complex structures and thus reveal much about the solar magnetic field at this point. The group 1944 is classified as one of the greatest of the last 10 years and was about 200 000km long. If this creates strong eruptions, as in the evening of the January, there is great excitement at sun fans, because the chance of visible aurora is also increasing for the central European region.
