                         Atlantic Magnetic Anomaly -SAMA is presented. The study of 
                         geomagnetic pulsations is important to help the understanding of 
                         the physical processes that occurs in the magnetosphere region and 
                         help to predict geomagnetic storms. The fluxgate mag-netometers H, 
                         D and Z, three axis geomagnetic field data from the Southern Space 
                         Observatory -SSO/CRS/INPE -MCT, S{\~a}o Martinho da Serra (29.42° 
                         S, 53.87° W, 480m a.s.l.), RS, Brasil, a were analyzed and 
                         correlated with the solar wind parameters (speed, density and 
                         temperature) from the ACE and SOHO satellites. A digital filtering 
                         to enhance the 2-7 mHz geomagnetic pulsations was used. Five quiet 
                         days and five perturbed days in the solar minimum and in the solar 
                         maximum were selected for this analysis. The days were chosen 
                         based on the IAGA definition and on the Bartels Musical Diagrams 
                         (Kp index) for 2001 (solar maximum) and 2008 (solar minimum). The 
                         biggest Pc-5 amplitude averages differences between the 
                         H-component is 78,35 nT for the perturbed days and 1,60nT for the 
                         quiet days during the solar maximum. For perturbed days the 
                         average amplitude during the solar minimum is 8,32 nT, confirming 
                         a direct solar cycle influence in the geomagnetic pulsations
