                         orthogonal geomagnetic field components data were acquired with a 
                         fluxgate magnetometer with 0.5Hz acquisition rate. Comparisons 
                         between the temporal evolution of the geomagnetic field intensity 
                         and the solar wind parameters for different phases of the solar 
                         cycle were analyzed. It was possible to identify fast changes in 
                         the geomagnetic field which may be correlated with stronger or 
                         wicker solar activity with important effects around midday in the 
                         local Ionosphere. This fact confirm the existence of relationships 
                         between the local geomagnetic variations and the solar activity. 
                         The periods of higher solar activity are related to a significant 
                         increasing in the flow of electrically charged particles in the 
                         atmosphere. As consequence of the physical and chemical phenomena, 
                         associated to these particles flow increases, are damages in 
                         satellites that orbit this region, as well as the induced electric 
                         currents in the Earth surface that causes damages in the electric 
                         power systems.",
