Abstract:
Solar wind (slow and fast components) and its extensions in the interplanetary space are governing and perturbing the planetary magnetospheres. The response of the terrestrial magnetosphere displayed as geomagnetic storms induces significant effects on the space and ground technological systems.
This paper analyses two geoeffective ICMEs during the maximum phase of solar cycle 24 (March 2013) and describes in detail the active regions hosting the CME. We will describe the behaviour of the fast solar wind that has interacted with the ICMEs. The B and Bz variability registered simultaneously with the speed and the density of the interplanetary perturbation will be discussed. Their role in the strength geomagnetic storm and the energy transferred to the terrestrial magnetosphere will be emphasized.
