Abstract: The southern Be star is a photometric variable with a rather large amplitude of more than 0.8 magnitude in the visual. From 176 photometric data in the Geneva System that cover six years we demonstrate the star is a biperiodic variable. The two periods are 8.929 and 2.824 days; mean light curves with these periods account for 44% and 22% of the variance, respectively. Colors and magnitudes vary in phase with respect to the first frequency, but not so with respect to the second frequency.
