%X Among the major challenges of the SpaceWeather community is the comprehensive knowledge of the electrodynamical processes occurring due to the Solar-wind and the magnetosphere coupling, in which substantial transfers of energy, moment and particles occur. As direct consequence of the enhancement of this kind of coupling, magnetic disturbances at the Earth surface related to a magnetosphere-ionosphere current system can be produced and they are possible to be recorded by magnetometers. This work aims to implement a tool to identify the behavior of the energy, i.e. impulsive variations, during the main phase of geomagnetic storms which are related to this complex current system. Instead of the use of a pos-processed index available the most of the time with a delay of months, for instance, equatorial geomagnetic index Dst, a real-time diagnosis has been proposed in order to identify geomagnetic storms. This diagnosis is based on a wavelet analysis technique to deal directly with raw data from a chosen magnetometer station.
