Particle response to the IP shock on 22 August 2021. Top panel: Solar wind speed (black curve, left axis), solar wind temperature (red curve, right axis, kT), solar wind number density (blue curve, right axis). Middle four panels: EPT foil (left) and magnet (right) observations by Solar Orbiter from different telescopes, as indicated in the upper right corner of each panel. The pitch angle is shown as a dot-dashed line (right axis). The colour bar on the right shows the intensity. Bottom panel: Magnetic field magnitude ∣B∣ (black curve, left axis), and polar (red curve, right axis) and azimuthal (blue curve, right axis) angles. The vertical dashed line indicates the IP shock arrival.
