Patrol-survey data on the intensity of forbidden-line O I emission at 630 nm in the night glow were obtained at the Abastumani observatory in periods when an intensification of F-region glow in the midlatitude ionosphere was observed visually from Salyut-6. An increase in the intensity of this emission during certain solar flares was detected. Calculations are made of concentrations of O1D formed in dissociative-recombination channels and through collisions with photoelectrons produced as the result of photoionization of the upper atmosphere by flare fluxes of solar radiation scattered in the geocorona. It is shown that dissociative recombination of O2(+) prior to flares fully determines the observed emission intensity at 630 nm.
