The colatitudinal positions of Region 1 (red) and Region 2 (blue) of the northern (top part of each panel) and southern (bottom part of each panel) polar ovals for the magnetic storm analysed in Fig. 1. The Region 1 and Region 2 colatitudes were estimated by analysing residual signal \(\Delta Y_{\mathrm{sm}}\) along Swarm A (top panel), Swarm B (middle panel) and Swarm C (bottom panel) tracks, respectively
