Short summary
During the most intense storm of solar cycle 24, the magnetosphere–ionosphere interaction, which is primarily associated with field-aligned currents (FACs), was much stronger than usual. Measurements onboard the low-latitude polar-orbiting Swarm satellites have shown that the intensities of FACs increase dramatically during the storm-time substorms. The extreme values of 1 s (7.5 km width) FACs reach 80 μA m−2. The lowest latitude of the FAC region is limited to 49–50 MLat.
