- Аннотация: We study the newly discovered variable star GSC 4560–02157. CCD photometry was performed in 2013–2014 at the Tien Shan Astronomical Observatory, and a spectrum was obtained with the 6-m telescope of the Special Astrophysical Observatory in June, 2014. GSC 4560–02157 is demonstrated to be an eclipsing variable star (P = 0.265359d). All its flat-bottom primary minima are approximately at the same brightness level, but the star's out-of-eclipse brightness and brightness at secondary minima vary considerably (by up to 0.6m) from cycle to cycle. Moreover, there are short-term (time scale of 0.03–0.04 days) small-amplitude brightness variations out of eclipse. This behavior suggests a cataclysmic nature for the star, which is confirmed with a spectrum taken on 2014 June 5. The spectrum shows numerous emissions of the hydrogen Balmer series, HeI and HeII.
