On the amplitude of the radio response of the active region magnetosphere to long-period natural oscillations of sunspots

The following has been indicated for the cyclotron emission of microwave sources based on a simple modeling of a unipolar sunspot magnetosphere by the magnetic monopole, submerged in subphotospheric layers, and a temperature, changing with altitude as hyperbolic tangent. At insignificant changes in the sunspot magnetic field strength, originating as a result of oscillations of a sunspot as an integrated structure, the oscillation amplitude (in percent) of brightness temperatures of the Stokes I and V parameters at a wavelength of 1.76 cm (NoRH) is an order of magnitude as large as the magnetic field strength amplitude. This amplitude is of the same order of magnitude as the field oscillation amplitude at a wavelength of 5.2 cm (SSRT).
