(Normalized) induced equivalent current function \({\varPsi }_2\) (currents formally assumed to flow at Earth’s surface), DIFI-2015b model, for April 1, \({\mathrm{{UT}}}=12\) and \(F_{10.7}=100\) SFU. \({\varPsi }_2\) is normalized by the maximum value for all seasons. A 8.2 kA current flows between the contours. The dip equator is depicted as a black line
