%X The Earths magnetic field varies in time scales of long and short periods, from seconds to millions of years. The variations with less than five years are mainly due to external sources, arising from the Sun-Earth interaction. The largest variations are associated with the dynamics process within the Planet. The main objective of this project is to study the characteristics of the geomagnetic pulsations at different phases of the solar cycle, as well as its relationship with the precipitation of charged particles in the region near of the South Atlantic Magnetic Anomaly (SAMA) center. The geomagnetic observations are carried out by a fluxgate magnetometer (saturated nucleus) installed at the Southern Space Observatory  SSO/CRS/CCR/INPEMCT(29.42° S, 53.82° W, 488m a.s.l), in São Martinho da Serra, RS, Brazil. The geomagnetic data are analyzed and compared with the pulsations observed in other stations outside the SAMA region, with emphasis for the geomagnetic station at the Vassouras Magnetic Observatory, Vassouras, RJ, from the Brazilian National Observatory - ON/MCT. Using a digital filtering, as a pass-band filter, with the function that only analyzes the continuous pulsations, it is detected the Pc5 (between 150-600 seconds and in the spectral region of 1.0 - 10 mHz). We analyze the differences between the geomagnetic variations observed in magnetically quiet days and magnetically disturbed days and its relation with the Earths Magnetic Field Intensity.
