The Return Flux (RF) sunspot model (Osherovich, 1982) imposes a restriction on the value of the vertical gradient of the magnetic field, dB/dz, analogous to a restriction implied by the self-similar sunspot model of Schliiter and Temesvary (ST). The maximum value of the gradient, (dB/dz),~ax, is sho

โฆ Synopsis
Some estimations for the vertical gradient of the sunspot magnetic field have been obtained under the similarity assumption. It is proved that the assumption is incompatible with large values of the vertical gradient. The greater the size of the sunspot is the smaller is its permissible value of dH/dz.

The potential models of the unipolar sunspot magnetic field are calculated on the basis of magnetographic measurements of the magnetic field made in the three spectral lines of different intensities, H c~, Ca 1 26103 and Fe 1 2 4808. The computed distributions of the magnetic field vector are compar
It is shown that the analytical solution of the equilibrium plasma equation which is a superposition of the axial-symmetric solution and the solution with helical symmetry can describe asymmetry of elements for a bipolar sunspot group.
