Sažetak
NW Ser is a bright (V=6.1-6.2), active Be star which is known to vary photometrically on a time scale of hours to days. Using both Hipparcos and ground-based photometry, and using light curve, autocorrelation, power spectrum analysis and phase dispersion minimalization techniques, we have concluded that the period is close to 0.46 days - a period typical of stars of this type, and in good agreement with the value of 0.488 days, recently determined by Hubert&Floquet from Hipparcos data. It is possible that the period is near twice tis value, but the evidence is not strong. We also find a period of about 5.5 days from both the ground-based and Hipparcos data.
