Recurrent ³He-rich solar energetic particle injections observed by Solar Orbiter at ∼0.5 au

We report Solar Orbiter observations of six recurrent solar energetic particle injections in 2022 March 3−6 at ∼0.5 au. All but one were associated with jets emanating from a plage near large sunspot active region 12 957. saw high 3 He and Fe enrichments minor no or lower enrichments. Furthermore, the event highest enrichment showed more compact configuration underlying photospheric magnetic field. The higher fluences as well harder spectra seen simultaneous jet wider eruption. However, this case, energy buildup time source might be required to produce such spectra. Extreme-ultraviolet images revealed number intersecting loops base not 1 au that precondition for events.
