Event 2: EUHFORIA snapshots of Run 03 (panel a) and Run 05 (panel b) B_clt in the heliographic equatorial plane and in the meridional plane that includes the Earth. Panel c: sketch showing the trajectory of the Earth through the spheromak magnetic structure (continuous black line) in Run 03 (red dot) and Run 05 (blue dot). The dashed black line shows the flux-rope structure as an elliptical object connected to the Sun. Panel d: sketch showing the magnetic structure of an elliptical flux rope (continuous black line), in relation to the Earth trajectory in the two runs. Here the dashed black line marks the spheromak structure. The actual trajectory of Earth is consistent with that marked by the red dot.
