             abstract = "A solar eclipse is a spectacular phenomenon resulting from a 
                         Sun\‐Moon alignment as viewed from the Earth. Eclipses have 
                         a great influence on the state of the ionosphere and trigger 
                         significant variations during this extraordinary event, as daytime 
                         sunlight turns to darkness and back again. Therefore, 
                         understanding how this dramatic solar\‐lunar event affects 
                         the Earth's atmosphere is of enormous importance. In this study, 
                         we took advantage of the proximity of a 2 July 2019 solar eclipse 
                         to the equatorial ionization anomaly (EIA) in order to investigate 
                         EIA dynamics during the eclipse total obscuration as it made its 
                         first landfall over the South American continent. We found the 
                         following eclipse dynamic features (1) analogous to prior results 
                         at the EIA, a 57% enhancement of the total electron content (TEC) 
                         in the EIA crest during total obscuration in areas a few degrees 
                         to the north from totality; (2) a 35% TEC suppression along the 
                         path of totality to the south of the EIA (sub\‐EIA) crest; 
                         (3) temporal and spatial extension of the southern EIA crest; (4) 
                         enhancement of the fountain effect and associated with it vertical 
                         plasma drift in the magnetic equatorial region; and (5) unusual 
                         observation of TEC bite\‐out near the EIA crest prior to 
                         local eclipse onset.",
