The paper deals with the observation of gamma radiation of energy higher than 40 MeV, from the cosmic source in the Cygnus constellation, from which several flares of radio and IR emission were registered in September and October 1972. The results were obtained with a high-aperture gamma telescope with spark chambers, carried aloft with a high-altitude balloon. The measured value of the gamma flux from the source is given. It is indicated that the source may be variable.
