Wagner, R. M. ; Newsom, G. H. ; Foltz, C. B. ; Byard, P. L. Abstract Spectroscopic observations of SS 433 were obtained on ten consecutive nights in May 1981. Measurements of the equivalent widths of the spectral lines and Doppler shifts of the moving lines are presented. Not only does the six-day period in the wavelengths of the moving lines appear quite clearly, but the data strongly suggest that this period is decreasing at a rate of 0.00003 + or - 0.000011 days/day. In addition, large equivalent width variations of the stationary lines are observed.
