Star Name: GSC 0584-01373, USNO-A2.0 0900-20378238, 2MASS 23200944+0632222
Coordinates (J2000): 23 20 09.44, +06 32 22.3
Variability type: EW;   Limits, System: 14.65 - 14.81 (R);    
Period: 0.36611 d;   Epoch(min): JD 2454430.1837

During observations of the field of AC Psc (Kryachko et al., 2008), we discovered a new eclipsing variable star. Our observations were carried out in Astrotel-Caucasus observatory using a 300-mm Ritchey-Chretien telescope, equipped with an unfiltered SBIG STL-11000 CCD camera. In total, 132 images with 5-minute exposures were obtained on JD 2454430 - 2454479. For basic reduction for dark current, flat fields and bias, we used the MaxIm DL software. For variable-star search and photometry of the new variable, we applied VaST software by Sokolovsky and Lebedev (2005). The comparison star was USNO-B1.0 0963-0596875 (23:20:10.60, +06:20:55.1 (J2000); R1 = 14.46, R2 = 14.63), assuming Rcomp = 14.545. Based on our data and using Peranso 2.31 software (see, we found a period of GSC 0584-01373, P=0.36611 +/- 0.00031 days. MinII = 14.77 R.
