The position of bright knots of 30 flares at their very beginning relative to the high-resolution isogauss maps of the longitudinal component (H∥) and maps of the transverse component (H⊥) of magnetic field are considered for seven days during the passage of the active and large spot group in Sept. 1963 (see Table I and maps on Figures 1–8).The flare bright knots occur simultaneously in regions of opposite magnetic polarity, and the majority of these knots are adjacent to neutral lineH∥= 0, although not coinciding precisely with this line (Figure 9). Lenticular form of flare knots and the motions of bright material of flares is restrained by transversal fieldH⊥. Also flares are closely associated (83%) with so-called ‘bifurcated regions’, where specific crossing of transverse components takes place (Figures 4–5). There is well-expressed (80%) coincidence of flare knots with the strongest (positive or negative) electric currents as determined from the relationj=c/4πrotH. The relation of results obtained to some existing theories of flares is briefly discussed.
