Some results of measurements of energetic particle spectra in the interplanetary space at the distance 1.0-0.7 AU on the ''Venera 11, 12'' automatic interplanetary stations

Studied are the spectrum characteristics of the solar radiation and flares of solar cosmic rays. The experiments have been made with the help of multidetector telescopes positioned on the ''Venera 11'' and ''Venera 12'' automatic interplanetary stations. The data, obtained in September - December 1978 during the flight from the Earth to the Venus, have been used for analysis. The electron and proton fluxes have been recorded in the energy ranges from 50 to 500 keV and 0.8-20, 1.2-6.0 MeV respectively 18 increases in the fluxes of energetic particles have been recorded during this period, 9 increases may be caused by concrete solar flares. The events on 23.09, 8 and 9.10.1978 have been considered in a more detailed way. The energy spectra of particles of the above events are presented, as well as the time dependences of various-energy particle fluxes during flares on 8. and 9.10.1978. A problem of splashes of rigid electrons with the duration not longer than 20 min, recorded at the ''Venera 11, 12'' automatic interplanetary stations, is discussed
