Solar Orbiter energetic electron and ion measurements during the ³He-rich SEP period. Panel a: EPT (41.8–105.7 keV) 30 min electron intensities from the sunward pointing sensor. Dashed vertical lines mark the type III radio bursts listed in Table 1. Panel b: SIS 1.0 h H, ³He, ⁴He, O, and Fe intensities at 0.23–0.32 MeV nucleon⁻¹. Panel c: SIS mass spectrogram at 0.4–10 MeV nucleon⁻¹. Panel d: SIS 1/speed vs. arrival times of 2–70 AMU ions. Sloped dashed lines approximately mark the ion injections. SIS measurements are from both telescopes and averaged together. The gap around noon on November 19 was caused by EPD being shut down for software maintenance.
