Abstract

We present the results of measurements of the solar energetic particle (SEP) flows in the Earth polar caps obtained from KORONAS-I on April 14, 1994. The maximum energy of protons was 12 MeV and the maximum energy of electrons was 1.3 MeV. The asymmetry of the North-South flows was observed several hours after their peak intensity. We determined the propagation characteristics of SEP in the isotropic diffusion model. Although the SEP enhancement has not been related to the solar flaring event, the genetic relationship of this effect with one of the largest-scale dynamical events on the Sun measured from YOHKOH is obvious. The possible sources of particle acceleration are discussed.
