Bin Wang(Shaoxing, Zhejiang, China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 17.7) on a 40-s survey image (limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Dec.20.93169 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ). The new object approximately located at R.A. =13h 10m 07s.34 Decl.=+34°10'51".4(equinox 2000.0). Which is about 32.7" east and .8" south of the center of the UGC 8246. Nothing is visible at this position on archival images taken on Mar.31 (limiting mag 19.0 )or on the DSS from Jan. 10,1989(limiting mag about 19.8).
