Location of the reconnection regions in the XY plane when |B_IMF| increases from 10 to 250 nT for northward and southward IMF orientations. P_d = 1.2 nPa and T_sw = 1.8 × 10⁵ K. The color contour indicates the |B_IMF| value. The yellow (gray) star indicates the reconnection region on the DS (NS) for a southward IMF orientation. The yellow (gray) circle indicates the reconnection region near the North (South) pole for the northward IMF orientation.
