Abstract: We report observations of time-intensity profiles, pitch-angle distributions, spectral forms, and maximum energies of <500 keV/nucleon suprathermal (ST) H, He, O, and Fe ions in association with heliospheric current sheet (HCS) crossings by Solar Orbiter and Parker Solar Probe (PSP). We present detailed analysis of the evolution of the pitch-angle distributions and spectral properties during the crossings which have revealed, for the first time, important clues about the nature of ion acceleration via reconnection-driven mechanisms at the near-Sun HCS.
