A series of solar energetic electron (SEE) events was observed from 2022 November 9 to November 15 by Solar Orbiter, STEREO-A, and near-Earth spacecraft. At least 32 SEE intensity enhancements at energies >10 keV were clearly distinguishable in Solar

We present Solar Orbiter energetic particle observations of two ^3 He-rich events with features more clearly observed than in prior studies. The event of 2022 November 9 observed from 0.59 au contained hundreds of ultraheavy (UH; mass >78 amu) ions w

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 a large sunspot in active region 12 957. We saw large jets i

The origin of 3He abundance enhancements in coronal mass ejection (CME)-driven shock gradual solar energetic particle (SEP) events remains largely unexplained. Two mechanisms have been suggested - the re-acceleration of remnant flare material in inte

Solar coronal dimmings have been observed extensively in the past two decades and are believed to have close association with coronal mass ejections (CMEs). Recent study found that coronal dimming is the only signature that could differentiate powerf

Observations of energetic ions and electrons from STEREO and ACE have been used to investigate the longitudinal extent of particle emissions from 3He ‐rich solar energetic particle (SEP) events. In the event of 3–4 Nov 2008, ions and electrons we

[1] We attribute the great geomagnetic storm on 8–10 November 1991 to a large-scale eruption that encompassed the disappearance of a ∼25° solar filament in the southern solar hemisphere. The resultant soft X-ray arcade spanned ∼90° of solar l

[1] We study large-scale activity on the solar disk associated with a 24–26 November 2000 series of six recurrent major flares and “halo” coronal mass ejections (CMEs). The analysis is based mainly on the SOHO/EIT data, particularly by using pr

[1] It has recently been suggested by Cane et al. [2002] that a class of type III solar radio bursts, called type III-l, is reliably associated with intense solar energetic particle (SEP) events. They proposed that the causative electrons for these b

We examine the source regions of the largest prompt solar energetic particle (SEF) events (J(sub proton)>10 MeV >100 pr/sq cm/s/sr) occurring between 1992 and 2002. We find that the 25 such events originated in a broad spectrum of solar regions, rang
