Short summary
The Earth's radiation belts control the space environment, often affecting the GPS signal propagation and satellite operations. Intense fluxes of energetic particles can penetrate even below the inner belt near the Equator. We analysed electron penetrations under geomagnetic quiet conditions and found in the solar wind an external driver cause. Satellite observations prove that disturbance of the inner belt was associated with impact of plasma jets formed in the solar wind nearby the Earth.
