             abstract = "The energetic particle population in the radiation belts can be 
                         affected through the coupling between the solar wind structures 
                         and the Earths magnetosphere. When such particles precipitate into 
                         the upper atmosphere they may also affect both the ionosphere and 
                         the neutral atmosphere, especially at high-latitudes and the 
                         Southern Hemisphere Magnetic Anomaly (SHMA). Presently, the impact 
                         of the energetic particle precipitation into the highlatitude 
                         ionosphere is well understood. On the other hand, the direct 
                         impact into the SHMA ionosphere is still lacking in more 
                         information. Therefore, a case study (May 28, 2017) is selected 
                         during the strong geomagnetic-storm (Dst: -125 nT) associated with 
                         an Interplanetary Coronal Mass Ejection. The Van Allen Probes 
                         recorded a significant reduction on the radiation belts electron 
                         fluxes concomitant with a shock detected by ACE-satellite in the 
                         Interplanetary Medium. Particles in a wide range of energy levels 
                         were lost to the atmosphere. POES satellite data and FengYun 
                         series spacecraft 3C confirm a strong increase of the energetic 
                         particle flux in the SHMA region during this storm. Data from a 
                         digisonde installed near the center of the SHMA (29.68\◦S, 
                         53.81\◦W) show the type sporadic E-layer (Esa), unusual in 
                         low-latitudes, during several hours. The increase of charged 
                         particles in this region can be related to the generation of the 
                         Esa layers, which occurrence is associated with particle 
                         precipitation. We conclude that the radiation belt dynamics, as 
                         well as the particle precipitation on the SHMA region during this 
                         storm, are the main components responsible for the generation of 
                         the Esa layers over the Brazilian region.",
