A periodogram analysis of the radial velocities and absorption line strengths from IUE spectra of HD 50896 show evidence of the 3.766 day period usually associated with this star. The dominant line variations occur on time scales of ∼ 1 day but may be interpreted as higher order harmonics of the 3.766 day period.
