Solar flares and energetic particles [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Solar flares are now observed at all wavelengths from γ -rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares ...

Large gradual solar energetic particle events
Living Reviews in Solar Physics, 2016 Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic ( ∼ few GeV) energies are accelerated near the Sun in at least two ways: (1) by magnetic reconnection-driven processes during solar flares resulting in impulsive SEPs, and (2) at fast coronal-mass-ejection-driven shock waves that produce large gradual SEP events.

Analysis of SEP Events and Their Possible Precursors Based on the GSEP Catalog
The Astrophysical Journal Supplement Series, 2023 Solar energetic particle (SEP) events are one of the most crucial aspects of space weather. Their prediction depends on various factors including the source solar eruptions such as flares and coronal mass ejections (CMEs).

Dispersive Suprathermal Ion Events Observed by the Parker Solar Probe Mission
The Astrophysical Journal Letters, 2023 During Encounter 11, Parker Solar Probe observed a low-energy dispersive ions event of solar origin. The event was observed in the SPAN-I and IS⊙IS EPI-Lo sensors.

From the Sun’s south to the north pole – Ulysses COSPIN/LET composition measurements at solar maximum [PDF]
Annales Geophysicae, 2003 Based on elemental abundance ratios derived from the Ulysses COSPIN/LET measurements, we classified the energetic particle populations during and after the socalled Fast Latitude Scan – the time period during which the Ulysses spacecraft traveled

3He-Rich Solar Energetic Particles: Solar Sources [PDF]
Space Science Reviews, 2020 3He-rich solar energetic particles (SEPs), showing up to a 10,000-fold abundance enhancement of rare elements like 3He or ultra-heavy nuclei, have been a puzzle for more than 50 years. One reason for the current lack of understanding of 3He-rich SEPs is the difficulty resolving the source regions of these commonly occurring events.

Transmission and Emission of Solar Energetic Particles in Semi-transparent Shocks. [PDF]
, 2014 While major solar energetic particle (SEP) events are associated with coronal mass ejection (CME)-driven shocks in solar wind, accurate SEP measurements reveal that more than one component of energetic ions exist in the beginning of the events.

Current status and possible extension of the global neutron monitor network
Journal of Space Weather and Space Climate, 2020 The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to
