A. Price, AAVSO, reports on the discovery of a new cataclysmic variable (V = 10.49 ± 0.02) in Pisces by G. Pojmanski and the ASAS-3 survey on CCD images taken on Sept. 11.203 UT. Astrometry by A. Henden (1.0-m U.S. Naval Observatory telescope) gives its position as R.A. = 0h25m11s.087, Decl. = +12o17'12".25 (equinox 2000.0; ± 0".04). The new variable is within the uncertainty boundaries of 1RXS J002510.8+121725 and 2MASS 00251111+1217121. Nothing is seen at that location on twenty-two ASAS-3 images taken between 2002 Dec. 15.041 and 2004 Sept. 6.363 (limiting V magnitude 14). The variable is detected at mag 17.5 on a Digitized Sky Survey blue scan of a plate taken on 1992 Aug. 29. Fourier (+ CLEANEST) analysis of CCD observations by L. Cook (Concord, CA; unfiltered), A. Oksanen (Muurame, Finland; V), D. Boyd (West Challow, Wantage, Oxfordshire, England; V), and M. Koppelman (Golden Valley, MN; R_c) between Sept. 15.902 and 19.300 reveal superhumps with a period of 0.05689 ± 0.00001 day. The superhump period and lack of previously detected outbursts suggests classification as a U-Gem/WZ-Sge-type dwarf nova. Additional magnitudes: Sept. 15.824, 10.7 (P. Schmeer, Bischmisheim, Germany; visual); 19.868, 11.4 (E. Muyllaert, Oostende, Belgium; visual); 20.459, 11.58 ± 0.01 (Cook; unfiltered CCD).
