Synthetic images of the CME obtained by ray-tracing based on the GCS reconstruction parameters for two times corresponding to Fig. 3 (top) and to Fig. 4 (bottom). The left panels show the 3D reconstruction projected onto the solar equatorial plane: the dashed green line represents the Solar Orbiter look direction, and the blue lines delimit the Metis field of view. The right panels show the synthetic images corresponding to the Metis point of view.
