ALGORITHM FOR ANOMALY DETECTION IN COSMIC RAYS VARIATIONS IN PERIODS OF HELIOSPHERIC DISTURBANCES

In this paper author proposed an algorithm for detailed analysis of the variations of cosmic rays and allocation of local abnormal changes that occur during periods of heliospheric disturbances. The algorithm is based on a combination of wavelet transform and threshold functions. The efficiency of the algorithm In this paper is shown on the basis of neutron monitors data (author analyzed data from neutron monitor stations Apatity and Cape Schmidt). The analysis of the variations of cosmic rays during periods of increased solar activity was performed and abnormal changes that occur before and during the moments of strong geomagnetic disturbances were highlighted.
