Abstract
Based on the data from the global network of neutron monitors, by using the spectrographic global survey, we obtained the parameters of magnetospheric current systems in the 1998 May events. Within the axisymmetric model for the bounded Earth magnetosphere, we determined the DR (ring current) and DCF (magnetopause currents) parameters for the current systems, as well as their contribution to variations in the rigidity of the geomagnetic cutoff and to the Dst-index over the addressed period.
