Analysis of geomagnetic field data during periods of increased solar activity and magnetic storms

Abstract

Abstract We present and describe an automated method for analysis of magnetic data and the detection of geomagnetic disturbances based on wavelet transformation. The parameters of the computational algorithms allow us to estimate the characteristics of non-uniformly scaled peculiar properties in the variations of the geomagnetic field that arise during periods of increasing geomagnetic activity. The analysis of geomagnetic data on the eve and during periods of magnetic storms was carried out on the basis of the method according to the network of ground stations. Periods of increasing geomagnetic activity are highlighted which precede and accompany magnetic storms. The dynamic of variation of the geomagnetic field in the auroral zone is considered in detail.
