Abstract
Some of the weak solar proton events in which protons with energies E ≥ 10 MeV are registered by observers on the Earth are particles accelerated by shock waves in interplanetary space. They can be associated with flares and coronal mass ejections tens of hours before an observed increase in proton fluxes that inject particles into the process of subsequent acceleration in interplanetary space.
