             abstract = "The work presents some results of the impact of the September 3, 
                         2008 moderate geomagnetic storm in the ionosphere over the South 
                         American Magnetic Anomaly (SAMA) as seen by the South American 
                         Riometer Network (SARINET). This SARINET operates 12 stations over 
                         South America, some of them over the SAMA region. However, in this 
                         work we analyse the cosmic noise absorption (CNA) detected only by 
                         three imaging riometers and a single beam riometer. The data and 
                         analysis are for the imaging riometers installed at S{\~a}o 
                         Martinho da Serra (29.4º S, 53.1º W), Punta Arenas (53.0º S, 70.5º 
                         W) and Concepcion (36.5º S, 73.0º W) and for the single beam 
                         riometer installed at Trelew (43.1º S, 65.2º W). A comparison 
                         between the selected riometerss data showed that the CNA was more 
                         pronounced at S{\~a}o Martinho da Serra (SMR), which is the 
                         SARINET site located at the central region of the SAMA in South 
                         America. This pronounced CNA arises from an enhanced ionization in 
                         the lower ionosphere that was probably produced by the energetic 
                         particles that precipitated during the geomagnetic storm, as 
                         indicated by an enhancement of the electrons with energy around 30 
                         keV, measured by the Polar Operational Environmental Satellite 
                         (POES) with the Medium Energy Proton and Electron Detectors 
                         (MEPED).",
