                         solar eclipse that occurred on 14 December 2020 over the Brazilian 
                         sector. This event partially covers the south of Brazil, providing 
                         an excellent opportunity to study the modifications in the 
                         peculiarities that occur in this sector, as the equatorial 
                         ionization anomaly (EIA). Therefore, we used the Digisonde data 
                         available in this period for two sites: Campo Grande (CG; 20.47 
                         degrees S, 54.60 degrees W; dip similar to 23 degrees S) and 
                         Cachoeira Paulista (CXP; 22.70 degrees S, 45.01 degrees W; dip 
                         similar to 35 degrees S), assessing the E and F regions and E-s 
                         layer behaviors. Additionally, a numerical model (MIRE, Portuguese 
                         acronym for E Region Ionospheric Model) is used to analyze the E 
                         layer dynamics modification around these times. The results show 
                         the F1 region disappearance and an apparent electronic density 
                         reduction in the E region during the solar eclipse. We also 
                         analyzed the total electron content (TEC) maps from the Global 
                         Navigation Satellite System (GNSS) that indicate a weakness in the 
                         EIA. On the other hand, we observe the rise of the E-s layer 
                         electron density, which is related to the gravity waves 
                         strengthened during solar eclipse events. Finally, our results 
                         lead to a better understanding of the restructuring mechanisms in 
                         the ionosphere at low latitudes during the solar eclipse events, 
                         even though they only partially reached the studied regions.",
