Fig. 16
From: Two current systems in the preliminary phase of sudden commencements in the magnetosphere
Type H and L current systems at t = 5.5 min colored according to inertia 3 values in the same manner as in Fig. 3. The current lines are shown only in the area of \(\beta\)<0.2. The contour line colors change in increments of \(\pm 0.2\). The type L current from AH is not shown in this figure. The inset in the left-bottom corner shows an enlarged part of the footpoints of both current systems. The color scale of inertia 3 for the inset is in increments of \(\pm 0.05\)
