Scientific paper

Red and blue spectrograms and B and V photoelectric observations of the Be star 69 Ori are considered. Separate analyses of the blue and red radial velocities by means of a least squares periodogram method exclude any significant variability within a period of 1.28 days, although alternative periods of 0.56 and 5.0 days remain as possibilities. The photometric data also excludes the possibility of binary star eclipses as the source of variability.
