FEATURES OF MAGNETIC STRUCTURE OF SUNSPOTS GROUPS AT DEVELOPMENT OF SUSTAINED FLUXES HIGH ENERGY GAMMA RAY

Аннотация

The research of magnetic structure of sunspots groups which were sources of three highest values of
fluxes gamma ray with energy of photons >100 MeV for all the time of observations on Large Area Telescope
(LAT), on board the Spacecraft (SC) Fermi Gamma-ray is conducted. At the same time observed fluxes of gamma
ray had also the greatest duration of existence. For comparison, group of spots of similar magnetic class was
attracted, but in the absence in it of events that are sources of gamma ray. As a result of the analysis, a characteristic
feature of the structure of magnetic fields was revealed: it is that in these sunspots groups inside the region of one
polarity there is a very close location of the magnetic field of the opposite polarity. This occurs in the consequence of
the interpenetration of cores and umbrae, as concentrated magnetic field carriers, of one polarity inside the field of
another polarity. Observations show the existence of a rather long neutral line with very high magnetic field
gradients, which affect the growth of active processes in the sunspots regions and, most importantly, the growth of
proton acceleration efficiency on high-speed shock fronts and shock waves of CME.
Therefore, groups of magnetic class sunspots BD and BGD, having a structure of close interweaving of magnetic
fields of opposite polarities, exhibit extreme activity and are proposed to allocate them into special subclasses - BDe
and BGDe (extreme). In the absence of such a property in the magnetic field structure, there is no significant
enhancement of activity in the sunspots groups of BD and BGD classes.
