Observations by Parker Solar Probe of a 3He-rich Solar Energetic Particle Event at 14 RS

Just after orbit 12 closest approach, on 2 June 2022 at a distance of 14 RS, the Integrated Science Investigation of the Sun (ISʘIS) observed a 3He-rich solar energetic particle (SEP) event. The event was associated with an active region just over the east limb (as viewed from Earth), which erupted with an occulted C1.2 class x-ray flare and a coronal mass ejection (CME) traveling ~350 km/s. PSP observed a type III radio burst associated with the flare, followed by a type III storm. After the initial dispersive SEP event, ISʘIS observed a second enhancement of energetic particles contained within the associated CME as it passed over the spacecraft. Comparisons of these two populations provide information regarding the acceleration of particles at the Sun as well as trapping or acceleration within the CME structure as different components of an individual solar event.
