Solar flare X-radiation and high-energy particles according to observational data from Venera-13 and Venera-14 automatic interplanetary stations

Venera-13, 14 data obtained from November 1981 to April 1982 are used to examine the correlation between bursts of hard solar X-rays (energy exceeding 0.055 MeV) and solar-cosmic-ray (SCR) flares. Data on solar flares in H-alpha, thermal X-rays, and Type 3 radio bursts were used in the analysis. It is shown that the amplitude of flare-electron intensity (energies exceeding 1.0 MeV) is best correlated with flare importance in the thermal X-ray range (r = 0.8 + or - 0.03). The use of this importance makes it possible to construct solar-longitude dependences of flare electrons and to assess the solar-longitudinal interval of flares in which coronal-propagation effects can be neglected. A practically linear correlation is found between SCR electrons with energies of tens of keV and thermal X-rays.
