Flares are common in the solar corona, ranging from one per week during solar minimum to several per day during solar maximum. These flares are associated with large plasma ejections and can produce very energetic particles in only a few minutes (electrons up to several MeVs and protons up to several hundred MeVs). Two probes have launched in recent years (Solar Orbiter, Parker Solar Probe…) towards the solar corona to study the physical processes involved in the acceleration of high-energy particles. These multipoint observations allow to follow the 3-D evolution of CMEs and the in situ measurements to study the spectra of accelerated particles. These particles represent a threat to human activity in space. A better understanding of the particle acceleration processes is essential to the development of better space weather that will allow the prediction of particle events.
