Solar Energetic Particles

Abstract

In this brief review, we summarize the current state of knowledge of solar energetic particles. This includes energetic particles contained within the site of solar flares that are responsible for X-ray, γ-ray and neutron emission and particles accelerated at high coronal altitudes and in interplanetary space by travelling disturbances such as coronal mass ejections. Special emphasis is placed on those particles directly or indirectly associated with neutron monitor signals.
