An experimental study of the propagation of solar electrons with energyEe > 30 keV was carried out. Measurements were made during the period 1972-1974 using the ‘Prognoz’ satellite-borne instruments.

A two-component structure of electron fluxes was found. The fast component, rather well-observed after solar flares of minor importance, consists of a compact beam of electrons propagating without scattering inside a narrow cone with an opening ⩽10° along interplanetary magnetic field lines. Characteristics of this component are given.

Peculiarities of the slow or diffusive component of electron fluxes are compared with the diffusive component of solar protons. It is shown that the diffusion coefficient for non-relativistic electrons is the function of the number of particles injected in the event. A model of ‘coherent’ propagation of non-relativistic electrons is offered, which takes into account the presence of the fast and slow components and their interaction with solar wind plasma oscillations.
