                         belts affect the upper atmospheres ionization level through the 
                         low-energy Electron Precipitation (EP). The impact of low-energy 
                         EP on the high-latitude ionosphere has been well explained since 
                         the 1960s decade. Conversely, it is still not well understood for 
                         the region of the South American Magnetic Anomaly (SAMA). In this 
                         study, we present the results of analysis of the strong 
                         geomagnetic storm associated with the Interplanetary Coronal Mass 
                         Ejection (May 27-28, 2017). The atypical auroral sporadic E layers 
                         (Esa) over SAMA are observed in concomitance with the hiss and 
                         magnetosonic wave activities in the inner radiation belt. The 
                         wave-particle interaction effects have been estimated, and the 
                         dynamic mechanisms that caused the low-energy EP over SAMA were 
                         investigated. We suggested that the enhancement in pitch angle 
                         scattering driven by hiss waves result in the low-energy EP 
                         (\≥10 keV) into the atmosphere over SAMA. The impact of 
                         these precipitations on the ionization rate at the altitude range 
                         from 100 to 120 km can generate the Esa layer in this peculiar 
                         region. In contrast, we suggested that the low-energy EP 
                         (\≤1 keV) causes the maximum ionization rate close to 150 
                         km altitude, contributing to the Esa layer occurrence in these 
                         altitudes.",
