Abstract
Simultaneous observations by the ESA satellite COS-B show that the 2-12 keV X-rays and 150-5000 MeV gamma-rays of Cyg X-3 are negatively correlated. A clear gamma-ray image of Cyg X-3 can be obtained between June 1977 and June 1980, when the X-ray emission was low, to yield a flux of P(E > 100MeV) ~ 1 × 10 -6cm -2s -1.
