abstract = "This work presents an analysis of the ionospheric responses to the
solar eclipse that occurred on December 14, 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°
S, 54.60° W, dip 23° S) and Cachoeira Paulista (CXP, 22.70° S,
45.01° W, dip 35° S), assessing the E, and F regions, and Es 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 Es 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.",
