Study of the impact of the CIRs on the magnetospheric current system using the magnetic indices as proxies
Abstract
A magnetosphere is an isolated sphere dropped inside the solar wind where it is in equilibrium. When a solar wind structure impact the magnetosphere, then, the equilibrium is broken and the magnetospheric current system reacts to prevent a magnetospheric collapse. The CIRs are not considered as the most disturbing solar wind structure, but the evolution of the magnetic indices indicate that the magnetosphere is disturbed deeply. Moreover, the study of the radiation belts fluxes show disturbances and increasing of the high energetic particles fluxes. Using the solar wind data at L1 during more than a solar cycle, and the magnetic indices, the impact of the CIRs on the magnetospheric currents will be studied as well as the intensity of the resulting substorm, its duration and the delay between the observation of the CIR and the maximum intensity of the substorm.
