Simpósio de Geomagnetismo do Brasil, 1. %X 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 São 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. %@mirrorrepository sid.inpe.br/mtc-m19@80/2009/08.21.17.02.53 %T Long Periods (1.0 – 10 mhz) Geomagnetic Pulsations with Solar Cycle in the South Atlantic Magnetic Anomaly Region %@tertiarytype Poster %@secondarytype PRE CI %K campo magnético. %8 5 a 10 junho de 2011 %@usergroup administrator %@usergroup ana.silveira %@group CRS-CCR-INPE-MCT-BR %@group DGE-CEA-INPE-MCT-BR %@group CRS-CCR-INPE-MCT-BR %@group %@group DGE-CEA-INPE-MCT-BR %@group CRS-CCR-INPE-MCT-BR %@group DGE-CEA-INPE-MCT-BR %2 sid.inpe.br/mtc-m19/2011/07.22.13.39.57 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@versiontype publisher %4 sid.inpe.br/mtc-m19/2011/07.22.13.39 %@documentstage not transferred %D 2011 %A Marchezi, José Paulo, %A Guimarães Dutra, Severino Luiz, %A Schuch, Nelson Jorge, %A Trivedi, Nalin Babulal, %A Silva, Andirlei Claudir da, %A Coelho Stekel, Tardelli Roman, %A Antunes, Cassio Espindula, %C Rio de Janeiro %@area CEA
