In situ SEP time profiles as well as plasma and magnetic field observations by BepiColombo (left) and PSP (right). Top: Energetic electron and proton temporal profiles observed from several energy channels and instruments. For SIXS, we use fluxes detected in side 2 of the detector. The flare eruption time is represented by the arrow on the upper x-axes. The vertical solid line and gray shaded area, respectively, indicate IP shock and ejecta transit observed by BepiColombo. Bottom: In situ plasma and magnetic field observations. The panels present, from top to bottom, the magnetic field magnitude, the magnetic field latitudinal and azimuthal angles, θ_{B − RTN} and ϕ_{B − RTN}, the solar wind speed, and the proton density, where RTN stands for RTN coordinates (IP structures as described in top panel). The pink lines represent the ENLIL simulation results.
