³He-rich solar energetic particle events observed on the first perihelion pass of Solar Orbiter

We report observations of five impulsive solar energetic particle (SEP) events observed inside 1 au during the first perihelion pass Solar Orbiter mission, which was launched in February 2020. These small were all reasonably associated with active regions from Earth but had rotated out view by time observations. Even though most small, their spectral forms, 3 He content, and association type III bursts convincingly identifies them as He-rich SEP properties similar to those previously at au. Three showed fast ion rise times, two long-lasting anisotropies consistent Compton-Getting effect.
