Solar Orbiter SIS measurements of the recurrent events. Top: 1 h H, ³He, ⁴He, O, and Fe intensity at 0.23−0.32 MeV nucleon⁻¹. Middle: mass vs. time at 0.4−10 MeV nucleon⁻¹. Bottom: 1/(ion-speed) vs. arrival times of 10−70 AMU ions. The measurements are from both telescopes and averaged together. Sloped solid black lines mark arrival times for particles traveling along the nominal Parker interplanetary magnetic field (IMF) line without scattering. Sloped dashed red lines approximately mark ion injections. The vertical dashed lines mark type III radio bursts associated with the ion injections.
