The trajectory-tracing technique was used to study the effect of perturbations in the geomagnetic field on cosmic ray particles arriving at the Earth. Variations of the cosmic ray cutoff rigidities at geomagnetic latitudes lambda = 47.78 deg and 54.77 deg (corresponding to the European neutron monitor stations Jungfraujoch and Kiel) were correlated with specific magnetic disturbances superposed locally upon the main geomagnetic field represented by a dipole field. The results show that for geomagnetic latitudes lambda 65 (that is, for McIIwain parameters L 5.6 r(e) the cutoff rigidities are most sensitive ot variations of the z-component of the magnetic field within geocentric distances r 2 Lr(e) sq cos Lambda and within a longitude sector extending from the longitude of the station up to 60 deg to 90 deg to the east of it. Within this region, magnetic perturbations being overhead and immediately to the east of the station are found to have the largest relative effect. The effects of magnetospheric current systems, corresponding to the Bostroem models, on the cutoff rigidities and the asymptotic directions at Kiel, Jungfraujoch and Rome are also discussed.
