Abstract: This research work emphasizes understanding the equatorial ionization anomaly morphology over the day and night sectors during the episode of the geomagnetic storm of April 23-24, 2023. For this, the latitudinal profile of total electron content over Indian (75°E) and American (75°W) are analyzed along with geomagnetic parameters, neutral winds (TIE-GCM), and CTIP modeled ⅀O/N₂. Interesting EIA features like latitudinal dispersion (poleward/equatorward bidirectional expansion) over the American sector and longitudinal elongation over the Indian sector under the composite effects of storm-induced electric fields and neutral winds) are observed. Also, an early and late sustained EIA is observed compared to typical noontime EIA.
