Abstract: We present results of reanalysis of old electrophotometric data of early typeclose binary system RY Scuti obtained at the Abastumani AstrophysicalObservatory, Georgia, during 1972-1990 years and at the Maidanak Observatory,Uzbekistan, during 1979-1991 years. It is revealed non-stable processes in RYSct from period to period, from month to month and from year to year. Thisvariation consists from the hundredths up to the tenths of a magnitude.Furthermore, periodical changes in the system-s light are displayed near thefirst maximum on timescales of a few years. That is of great interest withregard to some similar variations seen in luminous blue variable LBV stars.This also could be closely related to the question of why RY Sct ejected itsnebula.
