 Two new eclipsing variable stars USNO-B1.0 1411-0397871 and USNO-B1.0 1411-0397855 were discovered in the 9.4'x9.4' field of 1RXS J213344.1+510725 = RX J2133 which had been observed using the 1-meter Vihorlat National Telescope in the Astronomical Observatory on Kolonica Saddle. We preliminary registered these stars in the VSX ( and they got names VSX J213321.5+510857 and VSX J213320.0+510819, respectively. Types of variability were determined as EW for both stars. For the statistical modeling, the program FDCN (Andronov, 1994) was used, which allowed to determine degrees of the statistically optimal trigonometric polynomials and all photometric parameters, which are needed for the General Catalogue of Variable Stars, with their corresponding errors.

Simbad object(s): 1RXS J213344.1+510725, USNO-B1.0 1411-0397855, USNO-B1.0 1411-0397871,
