In situ SEP time profiles as well as plasma and magnetic field observations by Solar Orbiter (left) and STEREO A (right). Top: Energetic electron and proton temporal profiles observed from several energy channels. We use the sunward looking sectors of Solar Orbiters’ EPD/EPT and HET. For STEREO A, as not all instruments provide sectored measurements, we use omnidirectional data. The salmon shaded area indicates an SIR observed by STEREO A, while the stream interface is shown as a dashed line. Flare time and rest of IP structures indicated as in Fig. 12. Bottom: In situ plasma and magnetic field observations. Solar wind densities for Solar Orbiter are obtained from RPW/QTN measurements. Panels are the same as in Fig. 12.
