From 18 spectrograms, the orbital elements of this double-line spectroscopic binary were redetermined. In addition, from photoelectric observations, a light curve was derived. A general increase of brightness during one season accompanied by small amplitude and short time-scale variations were observed. The radial velocities of the visual companion have also been measured.
