| Resumo | The South Atlantic Magnetic Anomaly (SAMA), localized in the South Hemisphere, reaches almost all the region of the South Atlantic and extends longitudinally until the west coast of the South America. It is characterized as a region where the geomagnetic field has its lowest intensity and, therefore, there is a depression in its Field lines intensity. This depression anomaly occurs only in this region of the planet and its origin is attributed to the anti-symmetrical distribution of the electric currents in the interior of the planet. One of the consequences of the low intensity of the geomagnetic field in this region is that the energetic particles trapped in the Van Allens inner radiation belt can precipitate easily. The mirror point of the trapped particles over the SAMA is approximately 100 km of altitude, while is around 600 km in the magnetic conjugate point in the north hemisphere. In virtue of this, these energetic particles can precipitate over this region and dissipate their energy ionizing the atmospheric components, as occurs in the auroral region. This process is further enhanced during periods of geomagnetic storms and substorms. One of the usual methods to study the particle precipitation in the SAMA is through of the Imaging Riometer. The level of ionospheric absorption of cosmic noise is indirectly obtained from the data acquired with this equipment. From this data it is possible to infer the variation of the ionosphere electronic density. A higher ionospheric absorption indicates that an increase in the electronic density could have occurred in consequence of the energetic particle precipitation. Currently, there are three Imaging Riometer equipments in the SAMA region. The first one was installed in 1999 in the Southern Space Observatory - SSO/CRS/INPE - MCT, in São Martinho da Serra, Brazil, (29.4ºS, 53.8ºW). This observatory is strategically located near of the SAMA center, where the intensity of geomagnetic field is around of 23000 nT. In 2003 the second equipment was installed in Punta Arenas, Chile (53.1ºS, 71.0ºW). The third one was installed in Concepcion, Chile (37.5ºS, 72.7ºW). From these three equipments it has been possible to carry out studies to determine spatial scale and movement of the events of ionospheric absorption. The objective of this work is to present the analysis of data observed during a magnetically disturbed period with the Imaging Riometer installed at the Southern Space Observatory, as well as to give its brief description. |
