Short summary
We studied how solar eclipses affect the electric field in the atmosphere and the movement of charged particles above Earth near the magnetic equator. Using ground-based instruments in Peru, we found that eclipses can lead to significant changes, depending on weather conditions. These results help us better understand how solar events influence the near-Earth environment and its connection to the upper atmosphere.
