The bright Be star o And has been observed for over 90 years. Throughout this time numerous observers detected highly variable spectrum, photometric changes and substantial range of radial velocity of this star. Much effort has been devoted for period searching in these data. In the present study we collected all available (to our knowledge) radial velocities and photometric measurements in the visible region and tried to evaluate the reported periodicities.
