                         Precipitation (EP) to the atmosphere over auroral and South 
                         American Magnetic Anomaly (SAMA) regions. This EP into the 
                         atmosphere can cause an extra upper atmospheres ionization, 
                         forming the auroral-type sporadic E layers (Esa) over these 
                         regions. The dynamic mechanisms responsible for developing this 
                         Esa layer over the auroral region have been established in the 
                         literature since the 1960s. In contrast, there are several open 
                         questions over the SAMA region, principally due to the absence (or 
                         contamination) of the inner radiation belt and EP parameter 
                         measurements over this region. Generally, the Esa layer is 
                         detected under the influence of geomagnetic storms during the 
                         recovery phase, associated with solar wind structures, in which 
                         the time duration over the auroral region is considerably greater 
                         than the time duration over the SAMA region. The inner radiation 
                         belts dynamic is investigated during a High-speed Solar wind 
                         Stream (September 24-25, 2017), and the hiss wave-particle 
                         interactions are the main dynamic mechanism able to trigger the 
                         Esa layers generation outside the auroral oval. This result is 
                         compared with the dynamic mechanisms that can cause particle 
                         precipitation in the auroral region, showing that each region 
                         presents different physical mechanisms. Additionally, the 
                         difference between the time duration of the hiss wave activities 
                         and the Esa layers is discussed, highlighting other ingredients 
                         mandatory to generate the Esa layer in the SAMA region.",
