                         geomagnetic field in the region of the South Atlantic Magnetic 
                         Anomaly (SAMA), with its center located near the Southern Space 
                         Observatory - OES/CRS/CCR/INPE-MCT, in S{\~a}o Martinho da Serra, 
                         RS, (29.42°S, 53.87°O, 480m a.s.l.). The irregular pulsations are 
                         geomagnetic pulsation of low frequency, produced mainly by charged 
                         particles beams that penetrate the high atmosphere. This injection 
                         of particles in the ionosphere causes the establishment of current 
                         systems, creating an increase in the conductivity of the 
                         ionosphere, which in turn provides a shield increasing 
                         hydro-magnetic waves excited by the beam, causing the irregular 
                         pulsation that occur in the early stages of the development of a 
                         Magnetic Storms. For the study of impulsive events at SAMA, 
                         measurements of the geomagnetic field are being made through a 
                         Fluxgate magnetometer, low-noise (0.1nT), three orthogonal 
                         components H (North - South), D (East - West) and Z (vertical), 
                         recording changes in magnetic field strength every three seconds. 
                         The data obtained at SSO are processed and studied at the Solar 
                         Physics, Interplanetary Medium and the Magnetosphere Laboratory in 
                         the Southern Regional Space Research Center - CRS/CCR/INPE-MCT, 
                         Santa Maria, RS, in cooperation with the National Observatory - 
                         ON/MCT. The analysis of these physical processes is important for 
                         the scientific community, facilitating the understanding of the 
                         processes occurring in the Earth's magnetosphere..",
