PNV J23272715+0855391   2012 09 13.5680*  23 27 27.15 +08 55 39.1  13.9 U             Psc       I 0

2012 09 13.5680

Detected by K. Itagaki, Yamagata, Japan, during his SN search using 0.50-m F/6 refl. + CCD. It was below mag 19.0 on 2011 Oct. 19.559 UT. Note that this object is located in the constellation Pegasus, not Pisces. The discovery image can be seen at: http://www.k-itagaki.jp/images/pnv-psc.jpg. Possibly SDSS J232727.14+085538.7 (DR8, rmag = 22.028) is a quiescent counterpart. If it is correct, the outburst amplitude is ~8 mag, which is rather large for typical dwarf novae.
