Zhijian Xu(Nanjing,Jiangsu,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 17.4) on a 40-s survey image (limiting mag about 18.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Nov. 12.55094 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9). The new object approximately located at R.A. =19h 07m 00s.73 Decl.=+29°00'16".6(equinox 2000.0). Which is about 34.5" west and 6.5" south of the center of the PGC 62781. Nothing is visible at this position on archival images taken on Nov. 9(limiting mag 19.0), Oct. 30(limiting mag 18.7) or on the DSS from Jun. 21,1987(limiting mag about 19.8).
