In situ observations of the CME. In each panel, the shock front is delineated by the solid vertical line, and the magnetic flux rope boundaries are shown by the vertical dashed lines. Top panel: Solar Orbiter magnetic field data in radial-tangential-normal (RTN) coordinates, where the total magnetic field magnitude is shown in black and the magnetic field components, RTN, are in red, green, and blue, respectively. Middle panel: wind magnetic field data in RTN coordinates, displayed similarly to that of Solar Orbiter. Bottom panel: proton speed (black) and density (red) measured by Wind.
