Abstract : X-rays from Cyg XR-1 were observed on 3 May 1967 over the energy interval 20 - 130 keV. The estimated primary photon intensity from the star confirms a recently reported high x-ray flux at about 30 keV during May 1967. The differential x-ray spectrum of Cyg XR-1 is probably not just a simple power law or exponential function; however, a black-body curve can be excluded. (Author)
