- Аннотация: V sge is a spectroscopic binary with an orbital period of 0.514195d. The system's overall brightness was reported to vary erratically from 9 to 13 mag on time scale of months. The system displays a superimposed orbital light curve with both primary and secondary minima. Herbig et al. presented in 1965 a description of the system as a semi-detached one with the less massive component filling its Roche lobe, and the companion embedded oin a disk fed by gas passing through the vicinity of Li. More gas should be lost from the system by an unspecified mechanism. There have been many attempts to explain the model of V Sge in various alternative ways. Nevertheless, new papers and contributions are getting back to the original model given by Herbig et al. The observational material was obtained in the frame of the international photoelectric campaign. We have collected data from Skalnate Pleso, Hlohovec, Kryonerion, Brno and Crimea Observatories and reanalyzed the data provided by Mader and Shafter. Our first observations started in October 30, 1995 and have been continued to the present. We are presenting very preliminary results of the flickering study of this nova-like cataclysmic variable.
