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.
