“GEOMAGNETIC ACTIVITY is primarily driven by magnetic reconnection between the IMF and the terrestrial magnetic field. As the dipole is close to perpendicular to the ecliptic plane, it is primarily dependent on the southward component of the IMF, and the reconnection rate is proportional to the Y component of the motional electric field (E = −VSW × BIMF) of the solar wind.” (IMF= interplanetary magnetic field).
