THE PHOTOGRAPHIC OBCERYATION OF THE MAP OF THE GREAT MAGNETIC FIELD IN SOLAR ACTIVE REGION

  • This paper describes the feature of daily photographic observation of the map of the great magnetic field in solar active region. An example of the magnetogram shows that the agreement of the isophote (the outline of the umbra f2) with isoguass line (2000G) can be observed in complex magnetic region.
