During the extreme space weather event on May 10, 2024, a pronounced super-fountain effect was observed, driven by the prompt penetration electric field (PPEF) and pre-reversal enhancement (PRE) electric field. For this event, the SWARM-A satellite data provided unprecedented insights into the global impact of these electric fields due to its favorable orbit configuration which covered the local dusk sector. Observations revealed significant enhancements in the equatorial fountain, particularly over longitudes between $20^\circ$ E and 55$^\circ$W. Notably, this study also detected the first in-situ observational evidence of electron temperature (T$_e$) increases in the evening equatorial ionosphere during an extreme geomagnetic storm, with T$_e$ enhancements aligning with the super-fountain effect’s latitudinal extent. Additionally, contrasting effects were observed over a nearby longitude, highlighting the complex and localized nature of impact caused by extreme space weather.
