Abstract
The evolution of the solar magnetic flux and ultraviolet radiation in the two minima of solar activity are analyzed and compared with the results of the last minimum analysis. It was found that in all three minima the spots and flocculi (faculae) of both the old and new cycles associated with them appear in the selected longitude intervals. It indicates the existence of a nonaxisymmetric component of the magnetic field generated by the dynamo mechanism. It is shown that despite low values of magnetic fluxes in the sunspot activity region in the epoch of minima, they have a significant influence on processes in the solar chromosphere and corona, and, as a result, affect the variation of solar ultraviolet radiation.
