Solar Energetic Particle Events with Extremely High 3He Content Observed by Solar Orbiter

We performed a survey of ^3 He-rich events using observations from the Suprathermal Ion Spectrograph on the Solar Orbiter mission from 2020 to 2024. We identified 57 ^3 He-rich events, each showing clear ^3 He enhancements above the background and ^3 He/ ^4 He abundance ratios greater than 1 in at l...
