Geomagnetic Cutoff Variation Observed with TIBET Neutron Monitor
Abstract
From the TIBET neutron monitor observation, we have observed a strong correlation between cosmic ray intensity and geomagnetic disturbance. One of the strongest geomagnetic storm occurred at March 31, 2001 with this solar maximum period has shown the clear coincidence with the peak cosmic ray intensity and the time of Dst reached to the minimum. This feature indicates the short term changes of geomagnetic cutoff.
