ResumoMuch of South America is aected by the South Atlantic Magnetic Anomaly (SAMA), characterized by the minimum intensity of the geomagnetic eld on the Earths surface. Due to the presence of this anomaly, there is an increase in particle precipitation from the internal radiation belt that surrounds the planet, generating dierent aeronomic eects. In this study, we investigated the eect of this process on the amplitude of Pc3-Pc4 magnetic pulsations as a function of the distance from the center of the anomaly. Data from highly sensitive uxgate magnetometers (1 Hz acquisition rate) operated by the Brazilian Space Weather Program (EMBRACE) and INTERMAGNET in several locations in South America are used in the analyzes. Four magnetic storms were selected during the year 2015 and data from 7 days before (quiet period) and 7 days after each storm (most disturbed period, including the recovery phase) were ltered in the Pc3-Pc4 intervals. The results show a permanent amplication in the pulsation amplitude at the station closest to the center of the anomaly. It is proposed that this amplication is linked to the increase of the ionospheric conductivity in SAMA, caused by the enhanced particle precipitation from the radiation belt. Also, this eect is continuous in the anomaly region, being valid for both low level geomagnetic activity (quiet days) and high level geomagnetic activity (disturbed days).
