Temporal evolution of the deviation from the time-averaged bow shock position for the coordinates (Y_P, Z) in the laminar (a) and turbulent (b) case. The color code provides the deviation in d_i . The black circle points to the “bubble” appearing around (1000, 800) d_i in Figs. 2e, 3e, and 4e and reported in Fig. 7. The planar projection of the full 3D shock surface deviation at $t=250{\text{Ω}}_{\text{ci}}^{-1}$ is shown in panels c and d. A movie is available online.
