| Abstract | South Atlantic Magnetic Anomaly SAMA due to its weak total geomagnetic field F is known to be a sink of trapped charged particles from the inner radiation belt during both magnetically quiet and disturbed periods. Ionosondes, Riometers and VLF radio propagation monitoring experiments have shown ionospheric effects due to increase of ionization caused by the process of electron precipitation in the ionosphere of SAMA region during the quiet and disturbed periods. The enhanced ionization of the Brazilian SAMA region affects also the processes of the equatorial ionosphere. We have examined the records of geomagnetic variations during quiet periods and also at the time of sudden commencement (SC) in the horizontal component of geomagnetic field from the two stations situated in the SAMA region at the same dip latitude. The SC(H) amplitudes are found to be larger at a station situated close to the center of SAMA viz. São Martinho da Serra SMS (29.43° S, 53.82° W and 33° dip) compared to the station Vassouras (22°.40 S, 43°.65 W and 33° dip). It is possible that the observed amplitude enhancements of these impulses in H in the SAMA region may be caused by the differential increase of ionization due to the electrons precipitation that took place previous to the sudden impulse and/or due to the complex ionospheric processes connected with the prompt penetration of magnetospheric electric fields in the equatorial and low latitude E and F regions. |
