Spatial features of current systems of SFE-flares accompanied by gamma radiation

Based on statistical data and detailed analysis of geomagnetic response to the rigid electromagnetic radiation of the Х17 solar flare of September 7, 2005, spatial features of current systems producing the geomagnetic solar flare effect (SFE) are considered. During flares accompanied by intensive X-rays and gamma rays, SFE are shown to be globally observed including night hemisphere and high latitudes. Cause-and-effect relations of phenomena under consideration are discussed.
