| Abstract: | The results of microwave observations of the polarized emission of active regionsmade with the RATAN-600 radio telescope are
used to develop the method for determining the structure of the magnetic field of these regions at coronal heights. About
1000-G-strong magnetic fields are observed in the solar atmosphere at rather high altitudes (from 10 to 25 Mm). This result
is confirmed fairly well by the ultraviolet observations of magnetic loops, it is consistent with earlier radio-astronomical
observations of the magnetic field at the height of the transition region, and it corresponds as well, if interpreted in terms
of the dipole magnetic field model, to the vertical gradients of the photospheric magnetic field. |
