dc.descriptionA careful investigation of a CCD spectrum of the SB1 system kappa Cnc in the spectral region 3800 A - 8000 A resulted in the discovery of the lines of the secondary star. We then analyzed several short-wavelength range Reticon spectra obtained at different orbital phases to find additional radial velocities. The mass ratio is m_A/m_B = 2.2 +- 0.1 and, from binary spectrum-synthesis, the ratio of radii is R_A/R_B >= 2.
