  • Abstract: We review first several hours of post-impulsive-phase acceleration of high-energy particles in 9 different solar eruptions. Interplanetary proton and electron observations are employed along with data on secondary neutrons and γ-rays. Also employed are extreme ultraviolet, microwave and low frequency radio observations. We conclude that the post-impulsive-phase acceleration takes place close to Sun, at heliocentric distances about or below two solar radii, and may be associated with CME lift-off.
