We present an experimental study of flux creep in YBCO film at low temperatures (1.3 K < T < 25 K). A ring shaped film was used to obtain directly voltage-current characteristics of the film. It has been found that even very weak illumination greatly accelerates the flux creep at liquid helium tempe
