Variations in the geomagnetic cutoff rigidity of CR in the period of magnetospheric disturbances of May 2005: Their correlation with interplanetary parameters
The correlation between the rigidities of a geomagnetic cutoff, obtained using the global spectrographic survey method, and by trajectory tracing of CR particles in the magnetic field of the Ts03 Tsyganenko magnetosphere model (2001–2003) and the Dst variation and interplanetary parameters, was studied for the May 15–19, 2005, period of interplanetary and geomagnetic disturbances.
