             abstract = "The geomagnetic field is essential to the existence of life on the 
                         planet. The geomagnetic field acts as a barrier that protects the 
                         Earth from the high energy particles coming from the solar wind 
                         and outer space. The Earths magnetic Field undergoes changes on 
                         time scales of long or short periods, from seconds to several 
                         years (secular variations). The variations of about less than five 
                         years are of external origin, arising from the Sun-Earth 
                         interactions. The secular variations are associated with the 
                         processes within the Earth. The project is a study of the 
                         continuous pulsations Pc5 (150-600 seconds and frequency 2-7 
                         millihertz), and its relation to solar cycle and the South 
                         Atlantic Magnetic Anomaly (SAMA). Region where the Earths magnetic 
                         field undergoes continuous slow decrease of its total field 
                         strength, caused by the westward drift of the SAMA center and the 
                         geomagnetic axis away from the anomaly region. The lower intensity 
                         of the geomagnetic field permits easier precipitation of charged 
                         particles in the atmosphere over the SAMA region. The SAMA center 
                         is located in the vicinity of the Southern Space Observatory 
                         SSO/CRS/CCR/INPE-MCT, in S{\~a}o Martinho da Serra, RS, Brazil 
                         (29.42° S, 53.82° W, elevation 488m). The geomagnetic pulsations 
                         are the result of the interactions between solar wind charged 
                         particles and the magnetospheric plasma in the terrestrial 
                         ionosphere. These variations are detected by fluxgate 
                         magnetometers (saturated nucleus) installed at the SSO.",
