                         MCT, in S{\~a}o Martinho da Serra, (29.4°S, 53.8°W, 480m a.s.l), 
                         RS, Brazil, situated near the SAMAs center, which shows the lowest 
                         intensity of the geomagnetic field, and at the Vassouras 
                         Geomagnetic Observatory, RJ (22.40° S, 43.65° W), located on the 
                         SAMA edge region. The geomagnetic field three orthogonal 
                         components data, (H, D and Z) were measured with ''fluxgate 
                         magnetometers, with a 0.5Hz acquisition rate. The solar plasma 
                         speed and density data were obtained from the ACE satellite, 
                         located at the Lagrangian point L1, (1.5x10\⁶ km away from 
                         Earth). Comparisons between the intensity variation of the 
                         geomagnetic field and solar wind parameters for the different 
                         phases of the solar cycle are made. It is possible to identify 
                         fast changes in the geomagnetic field which are correlated with 
                         the solar activity, stronger or wicker, and its effects in the 
                         local Ionosphere, mostly around midday. Due to the low intensity 
                         of the geomagnetic field at SAMAs region, the periods of higher 
                         solar activity are related to an Atmosphere significant increasing 
                         in the flow of electrically charged particles. The physical and 
                         chemical phenomena associated to this increased particles flow may 
                         produce damages in satellites that orbit this region and inducing 
                         electric currents in the Earths surface causing damages in the 
                         electric power distribution systems.",
