Sun: particle emission

Peak-intensity energy spectra of intense solar energetic electron events measured with Solar Orbiter in 2020─2022 (Corrigendum)

Catalogue and statistics of > 100 MeV solar proton events during solar cycles 23─25 from SOHO/ERNE observations

*Context.* The SPEARHEAD (specification, analysis, and re-calibration of high-energy particle data) project, funded by the European Union’s Horizon Europe programme, enhances the accuracy and usability of high-energy particle measurements. It …

Peak-intensity energy spectra of intense solar energetic electron events measured with Solar Orbiter in 2020─2022

*Context.* The energy spectra of energetic particles offer valuable insights into particle acceleration processes. While the commonly observed spectral breaks in solar energetic electron (SEE) spectra could serve as fingerprints of the acceleration …

Comparing observations of closely located JUICE and STEREO-A spacecraft during the widespread 13 May 2024 solar energetic particle event

*Context.* Following its launch in April 2023, JUICE is now in its cruise phase to Jupiter, where it is scheduled to arrive in July 2031. JUICE carries a radiation monitor, namely the RADiation hard Electron Monitor (RADEM) to measure protons, …

A statistical study of energetic particle events associated with interplanetary shocks observed by Solar Orbiter in solar cycle 25

*Context.* We studied energetic particle intensity profiles observed by Solar Orbiter during the time period from April 2020 to April 2023, associated with the passage of interplanetary (IP) shocks. For our study we considered 58 IP forward shocks …

Electron and proton peak intensities as observed by a five-spacecraft fleet in solar cycle 25 (Corrigendum)

This article is an erratum for: 10.1051/0004-6361/202450945

The reason for the widespread energetic storm particle event of 13 March 2023

*Context.* On 13 March 2023, when the Parker Solar Probe spacecraft (S/C) was situated on the far side of the Sun as seen from Earth, a large solar eruption took place, which created a strong solar energetic particle (SEP) event observed by multiple …

A new method for determining the onset times of solar energetic particles and their uncertainties: Poisson-CUSUM bootstrap hybrid method

*Context.* Solar energetic particle (SEP) events are a type of space weather phenomena in which highly energetic charged particles are released from the Sun into interplanetary space by violent and eruptive phenomena, such as solar flares and coronal …
