| Abstract: | The variations in the geomagnetic cutoff rigidity in Irkutsk, Alma-Ata, and Beijing in October–November 2003 were calculated
using ground-based measurements of cosmic ray intensity from the worldwide network of stations and GOES spacecraft. The calculated
variations in geomagnetic cutoff rigidity are presented together with D
st variations of the geomagnetic field. The obtained results are compared to calculations performed using the Tsyganenko model
of the magnetosphere. |
