## 1 Introduction
[29] proved that eclipse-induced wind and temperature may significantly influence the ionospheric enhancement at EIA crests. Moreover, the dynamic processes that occur during a single eclipse are heavily influenced by the eclipse trajectory, time of day, location, synoptic, seasons, geomagnetic conditions, geophysical conditions, and solar variation [15; 32]. The trajectories of an eclipse can differ geographically and temporally depending on the observing altitude chosen, which could be important for researching ionospheric dynamics. Research has shown the importance of estimating the eclipse mask at the height of the ionosphere to be studied and not only working with the mask at the surface level [33; 34; 35]. Recently, several authors published TEC variations and observed anomalies related to solar eclipses in various geographic locations. [PERSON] et al. [36] presented the change in ionospheric plasma density during the annular solar eclipse on 26 December 2019, through multi-directional approaches by using ground-based TEC and space-based Swarm satellite and observed a depletion in TEC and \(N_{e}\) that is directly proportional to the solar obscuration function. Several authors have used different instruments (mainly VLF receivers) and computed \(N_{e}\) variation using LWPC simulation also [37; 38; 39; 40]. Including ionospheric responses to the partial and annular eclipse in different regions will help the reader to make comparisons with other cases and results obtained from other instruments. The partial solar eclipses of 15 February 2018 (PSE2018) and 30 April 2022 (PSE2022) were the first eclipses of 2018 and 2022, respectively. These eclipses were visible from over parts of Antarctica, the Pacific, and the Atlantic Oceans. Moreover, both eclipses were observed over southern South America in the afternoon ([[http://xjubier.free.fr/en/site_pages/SolarEclipsesGoogleMaps.html](http://xjubier.free.fr/en/site_pages/SolarEclipsesGoogleMaps.html)]([http://xjubier.free.fr/en/site_pages/SolarEclipsesGoogleMaps.html](http://xjubier.free.fr/en/site_pages/SolarEclipsesGoogleMaps.html)), last accessed on 20 August 2023). PSE2018 and PSE2022 happened over days with some levels of geomagnetic activity. Therefore, these two partial solar eclipses offer an excellent opportunity to study their effects on the regional ionosphere, under different geometric configurations of the eclipse and season of occurrence. Recent studies looked at the ionospheric effects of solar eclipses over South America and Antarctica. The 2 July 2019 total solar eclipse (TSE2019) occurred in the southern hemisphere winter (subsolar latitude \(\sim\)23\({}^{\circ}\)N) from 16.92 UT to 21.83 UT. TEC showed clear decreases (\(-\)40% to \(-\)25%) compared to the background ionosphere and a 57% rise near the southern EIA crest. TIDs presented wavelengths ranging from approximately 100 km to more than 200 km, with periods between 20 and 50 min. [PERSON] et al. [10; 31] reported a TEC enhancement effect that altered the equatorial electrodynamics. [PERSON] et al. [31] utilized an incoherent scatter radar in Jicamarca and 2500 GNSS stations localized over South and North America. [PERSON] et al. [10] studied 24 Chilean GPS station datasets localized north and south to the path of totality. The wavelet analysis of the VTEC time series showed the presence of strong AGWs of duration from 30 to 60 min at the GPS stations located the north of totality. [PERSON] et al. [41] used NASA's Global-scale Observation of Limb and Disk (GOLD) instrument aboard the SES-14 satellite in a geostationary orbit. They reported an important decrease in brightness around totality in OI 135.6 nm and N2 LBH band emissions when compared to baseline observations taken two days earlier. They also observed a large increase in the \(\Sigma\)O/N2 column density ratio (\(\sim\)80%) within the totality of the eclipse. [PERSON] et al. [42] presented the Andes Lidar Observatory (ALO), TIMED/SABER temperatures, and ionosonde electron density measurements. [PERSON] et al.
