Magnetic field measurements (absolute upper panels; B_x, B_y, and B_zlower panels) by Venus Express (top 2 panels) and STERO-A (bottom 2 panels) around the time of the CME arrival at those spacecraft. The in situ shock arrival is marked with a vertical black line and the flux rope signatures at Venus Express and STEREO-A are shown in grey-shaded regions. Data gaps in the Venus Express time–series reflect magnetospheric crossings that have been removed. The spike half way during the flux rope passage from Venus Express is associated with the Venus magnetosheath crossing that was not fully filtered out in the provided data.
