June-July 1974 Proton-Flare Region. I. Individual Stages of Its Background and Local Magnetic Field Development
Abstract
Evolutionary characteristics of the large-scale magnetic field pattern producing the June-July 1974 proton flare region are described. The region's space and time relation to the intersection of two different magnetically active longitudes is estimated, and its individual development stages are demonstrated. The process of successive complication of local magnetic field producing the proton-flare region and its growth of complexity in frame of the background magnetic field continuous redistribution are studied. The development of the June-July 1974 magnetic situation and that of the August 1972 proton-flare region are compared, finding many similarities although the events occurred at distinct stages of the solar cycle with different situations of activity density and with different latitudes.
