Abstract

We report Solar Orbiter observations of six recurrent solar energetic particle injections in 2022 March 3–6 at ~0.5 au. The injections were associated with jets emanating from a plage near a large sunspot in NOAA active region 12957. We saw large jets in injections with high 3He and Fe enrichments and minor jets in injections with no or lower enrichments. Furthermore, the event with the highest enrichment showed a more compact configuration of the underlying photospheric magnetic field. The higher fluences as well as harder spectra were seen in the event with a wider jet-like eruption. However, in this case, the buildup time might be required to produce such spectra. Extreme ultraviolet images from Solar Orbiter revealed a crisscrossing network at the base of jets not seen from 1 au that might be suitable for the recurrent events.
