Abstract:
Inhomogeneities of the interplanetary magnetic field (IMF), initiated from
the Sun, influence cosmic ray (CR) fluctuations. An attempt to define the
index of cosmic ray fluctuation variability based on 5-min data from two
neutron monitors is made. It is suggested that the integral of the power
spectrum density of cosmic ray fluctuations is used over time scales where the
interplanetary magnetic field strongly influences cosmic rays at neutron
monitor energies. This integral P1 ("the cosmic ray fluctuation variability
index") can be employed as one of the parameters in predicting geomagnetic
activity.
