ASAS 002511+1217.2
     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 magnitude
V = 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 (Oxon,
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 AAVSO observations:  Sept. 19.868, 11.4 (E. Muyllaert,
Oostende, Belgium; visual); 20.459, 11.58 +/- 0.01 (Cook; unfiltered CCD).
