Annotation
A short-term (up to 12 h) increase of the intensity of solar cosmic ray protons with energy $E>1$ MeV on April 11—12, 1990 according to the data recorded at the IMP-8 artificial Earth satellite is considered. The curve has two peaks. They are interpreted as ensembles of particles located in traps, the first peak corresponding to particles located in a heliospheric loop trap, and the second one, to particles in a trap behind the shock wave front.
