Spiral structure of the magnetic field in AO 0953 over a stable spot.
A two-dimensional high-altitude structure of the coronal magnetic field, with the power tube extending up the ~0.4-wide spiral was observed over a stable spot in the active region AO 0953. The magnetic field of around 600Gs is located at a rather high altitude in the solar corona (up to 25 thousand km). Radio astronomical multifrequency polarization observations of sources with the RATAN-600 were used.
In collaboration with St. Petersburg University.
