Parameters of Magnetospheric Current Systems during Geomagnetic Disturbances of May, 1998

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Parameters of the systems of magnetospheric currents in events of May, 1998, are obtained using data from the spectrographic global survey by the global network of neutron monitors. Systems of currents in the magnetopause and the ring current of the inner magnetosphere are determined using an axisymmetric model of the Earth’s limited magnetosphere, along with their contribution to the Dst index and variations in the rigidity of the geomagnetic cutoff over the considered period.
