Results are presented for radio and limited optical spectroscopic observations of the peculiar emission variable star SS 433, which appears to be associated with the X-ray source A1909+04 and the supernova remnant W50. The radio source is nonthermal and shows clear evidence for variability on a time scale as short as a few hours. Neither linear nor circular polarization was detected. The optical spectra indicate intense Balmer and other lines superimposed on a red continuum, with evidence for variability in the H-beta profile. The significance of these observations is briefly discussed.
