Abstract
The Energetic Gamma Ray Experiment Telescope (EGRET) aboard the Compto n Gamma Ray Observatory observed the Cygnus region in 14 different vie wing periods during 1991 May to 1994 July. We present here our results on unpulsed and pulsed emissions of gamma rays at E > 50 MeV from Cyg X-3. While we detect a gamma-ray source consistent with the position of Cyg X-3, there was no evidence for the characteristic similar to 4. 79 hr periodicity observed in X-rays and infrared.
