Case I: polar contour view of evolution of the FAC power \({\text{log}}\left( {J_{{||}}^{2} } \right)\) in northern hemisphere at \(r = 4~R_{{\text{E}}}\) from \(t = 160~~\Omega _{{i0}}^{{ - 1}}\) to \(t = 190~~\Omega _{{i0}}^{{ - 1}}\). The azimuthally tailward moving FAC signatures along the closed field lines corresponding to \(L~\sim ~6-8~R_{{\text{E}}}\) is tracked with purple circles with their peaks marked by cross-dotted targets. Note that the Region-1 type current shown in Fig. 10 are marked by black circles
