Is shown that the amplitude of a wave from sources located near to a surface of the Sun, amplifies in a sunspot, and the amplitude of a wave from deep sources varies unsignificantly at passage through a sunspot. It was received that the various mechanisms of heating are possible at different stages of development of solar flare. two groups of background magnetic fields with the differing characteristics are allocated On the Sun. The research of rotation of solar active regions, plages and coronal holes Is carried out on observation in line HeI. Monitoring of three kinds of the solar data was carried out. The multifractal index for the description of evolution of solar active regions is offered. It grows with increase of complexity of magnetic structure of active region. Modeling distribution of acoustic waves from dot sources in the subphotospheric layer of the Sun was carried out. Is shownthat the amplitude of a wave from sources located near to a surface of the Sun, amplifies in a sunspot, and the amplitude of a wave from deep sources varies unsignificantly at passage through a sunspot. It was received that the various mechanisms of heating are possible at different stages of development of solar flare. two groups of background magnetic fields with the differing characteristics are allocated On the Sun. The intensity of magnetic fields of group I are equal to + (3 -10)Gs. The intensity of magnetic fields of group II are equal to +(75 - 100) Gs. The research of rotation of solar active regions, plages and coronal holes show that rotation of structures with the several periods is observed in one latitude, and each period is present in several next latitude zones. The picture of rotation is asymmetrical concerning equators. The division coronal holes (CH) on two classes is found: open and closed CH. The high-velocity flows of a solar wind are connected, basically, with open CH. Product Description popup.authors popup.nrat_date 2020-04-02 Close
