Magnetic reconnection plays a key role in transporting plasma and magnetic energy in Earth's magnetosphere and ionosphere, driving space weather dynamics. The rapid plasma transport toward Earth generates plasma waves that scatter electrons, leading to electron loss into the ionosphere and the atmosphere via collisions with neutrals. We show that this wave‐driven electron loss with energies less than 1,000 electron volts produces dynamic red auroral emissions. This low‐energy electron precipitation will heat the ionosphere's F region, altering chemical reactions and plasma density. These changes then affect ionospheric conductivity that determines currents, electric potentials, and neutral wind dynamics in the ionosphere and thermosphere. Understanding these processes helps us better predict space weather impacts on communication, navigation, and satellite operations.
