Abstract

The study examined a chain of phenomena from the Sun to the Earth, which allows to study the mechanism of geoeffectiveness of eruptive prominences propagating from the Sun inside the CME (coronal mass ejections). An eruptive prominence ejected into the solar wind moves with its speed towards the Earth in the form of a DSEP (diamagnetic structure of an eruptive prominence). The contact of the DSEP with the magnetosphere leads to its compression and the passage of the DSEP substance into the magnetosphere. The duration of a magnetospheric disturbance in the form of polar auroras on the dayside, a global amplification of current systems, an increase in charged particle fluxes in the radiation belts, and the generation of irregular pulsations of the Pi2-3 type is determined by the duration of the DSEP. A diagram of the geoeffectiveness of the DSEP has been constructed. The resulting scheme is confirmed by statistical studies of the DSEP in different years of solar activity.
