Abstract
It has been shown that the cold component of CI Cyg eclipsing binary system is a variable star. The amplitude of its light variations is close to 0m.4 with the time interval of 40–60 days.This star being the red giant M4 can be attributed as SR type variability. The light variations is caused by its temperature variations.
