Wind spacecraft observations of an ICME ejecta and a preceding shock and sheath region at 1 au on 2020 April 20. Panel (a) shows the magnetic field (B) magnitude and Geocentric Solar Ecliptic (GSE) components of the field; panel (b) shows the magnetic field azimuthal (ϕ_B) component, and panel (c) shows the magnetic field latitudinal (θ_B) component with respect to the ecliptic plane; panel (d) shows the proton speed (∣V∣); panel (e) shows the proton density (n_p); and panel (f) shows the electron number flux at 165 eV energies for different pitch angles (PAs). The vertical lines indicate the shock (magenta), the ICME ejecta leading edge (blue), and the four HCS crossings (cyan).
