Basing on measurements of cosmic rays at the worldwide network of stations, we calculate variations in the planetary system of geomagnetic cutoff rigidity for the 2015 June moderate geomagnetic storm. Using the axisymmetric model of the limited magnetosphere taking into account magnetopause currents and the ring current, we determine the distance to the subsolar point and the ring current radius, as well as the contribution of the ring current to variations in the geomagnetic cutoff rigidity and to the Dst index.

Primary Cosmic Rays

The energy spectrum of electrons in the primary cosmic rays was measured at a location where the vertical geomagnetic cutoff rigidity is 11.5 GV, using a balloon-borne counter system. The differential spectrum was determined in the energy range from 13 to 50 GeV and is represented by a power law with exponent −2.4 ± 0.6. This result is consistent with a spectrum extending smoothly from lower energies with the same slope.
