Scientific paper

Coordinated optical spectroscopy, UBV photometry, and radio continuum measurements of SS 433 were made on four consecutive nights in November 1979. An apparently correlated anomaly of both moving spectral features of the star was found while the V color photometry revealed intensity variations of up to 0.4m. Significant radio flux density variation was measured at 2.7 GHz, although the intensity remained constant at 10.7 GHz. No linearly polarized radio emission was detected. No correlation was found between the radio and optical measurements reported here, but a possible correlation between the spectroscopic 165-d period and the radio spectral index is described.
