In situ measurements at SolO (left) and Wind (right). The magnetic field strength; components in RTN coordinates; the solar wind proton number density, temperature, and speed; and the pitch-angle distribution of suprathermal electrons at ∼265 eV (only at Wind) are shown. At SolO, the three vertical dashed lines indicate the shock boundary and the front and rear boundaries of the magnetic ejecta. At Wind, the first two dashed lines indicate the shock boundary and the ejecta front boundary, while the third and fourth lines correspond to two potential rear boundaries (see text for details).
