Abstract

The solar proton event of 27.08.2022 was recorded by spacecraft near the Earth, as well as by the Parker Solar Probe spacecraft, located at 0.38 AU from the Sun. During this event, a rare phenomenon was observed, the acceleration of protons to energies of tens of MeV in interplanetary space presumably between the converging shock fronts. An unusual delay in the fluxes of solar protons with energies above 10 MeV was also observed, as measured by satellites in Earth orbit, compared to the proton fluxes measured by spacecraft at the L1 Lagrange point.
