Abstract

Differences of magnetic field flows of “+” and “–” polarities i.e. the imbalance of magnetic fields, for 26 years are investigated, since January, 1, 1977 till September, 30, 2003. As the initial material synoptic maps of the longitudinal vector strength of the Sun magnetic field received in Kitt Peak National Observatory (USA) and kindly given to us by Dr. J. Harvey have served. The imbalance of magnetic fields cyclicity features, the deviations from dipole structure of the Sun magnetic field are determined. The contribution of latitude zones and of different strength fields to the general magnetic flux from the Sun is found. The last characteristic was compared with the Sun’s mean magnetic field (MMF) obtained from the observations of the Sun as a star.

The received results testify that the imbalance is one of physical characteristics of the Sun. The confirmations of such conclusion are:

  • the stringent legitimacies of the Sun dipole structure changing;
  • the complicated character of the imbalance cyclicity i.e. multiplicity of cycles;
  • the solar character of MMF changing;
  • the distinction of two classes of magnetic fields under the imbalance characteristics.
