A coordinated campaign of radio, optical, and x-ray observations of the bright x-ray source Cygnus X-1 took place August 7–21, 1977 under sponsorship of Commission 42 of the International Astronomical Union. Radio flux measurements, optical spectra, photometry, and polarimetry were obtained during this period by ten groups from Canada, Great Britain, the Soviet Union, and the United States. The x-ray flux was monitored continuously by the SAS-3 satellite between August 11.0 and 17.0.
