Upper panels: Positions of the spacecraft during events 1 and 2 from Solar-MACH (Gieseler et al. 2023). The location of Solar Orbiter is indicated by a blue dot. The arrow shows the direction of the associated solar flare. The Parker spiral magnetic field line corresponds to an assumed solar wind speed of 400 km/s. Lower panels: Corresponding halo CMEs observed by the LASCO-C2 coronagraph on board SOHO for both events.
