69 Ori (B5 V) was discovered as a Be star in 1976 (Doazan et al., 1977). We observed this object at the Merate Observatory during the periods Nov. 77. - Jan. 78 - Jan. 78 and Oct. 78 - Feb. 79 obtaining 20 red spectrograms and 25 blue ones with a dispersion of 35 Å/mm. We performed also B and V photo-electric observations during 12 nights altogether. The results from the red spectra and the photometric measurements have been discussed by Bossi et al. (1981).
