- Аннотация: We present the results of our new observations of GSC 01374-01131, a recently discovered high-amplitude Scuti (HADS) star for which, in 2013, we detected an eclipsing component of the light curve in the Catalina Surveys data. We acquired new CCD photometry in Johnson's B, V, and R bands for this star, improved the periods of the eclipses (P_e = 5.96857 d.) and of the pulsation (P_p = 0.08494573 d.) and other parameters of the light curves. GSC 01374-01131 is an eclipsing binary of the Algol type (EA); one of its components is a pulsating HADS star. Currently, GSC 01374-01131 has the lowest depth of the main eclipse (A_e = 0.13 m.) among all known HADS stars in eclipsing binary systems, comparable to the observed pulsation amplitude.
