June-July 1974 proton-flare region. II

Studies of changes with time of the background magnetic field areas not only confirm the results obtained in the first part of the paper, dealing with the investigation of the morphological development of the large-scale June-July 1974 proton-flare region related magnetic patterns, but also demonstrate the physical unity of this whole complex evolutionary process and its relation to the cyclic magnetic field generation in the Sun. The fast disintegration of the whole large-scale magnetic field figure and a complete disappearance of its sunspot, flare and green-corona activity follows during three-four rotations after the proton-flare events. For the explanation of this, the mechanisms have to be looked for which either transport magnetic field lines into the upper layers of the solar atmosphere and the interplanetary space, or which dissipate them without observable solar activity.
