Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag 16.6 at discovery mag) on a 40-s survey image (limiting mag about 19.8)taken by Xing Gao in Xingming ObservationSky Survey(C42) around May. 19.70152 UT, 2015. using an unfilted CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =16h 02m 51s.28 Decl.=+47o13'29".2(equinox 2000.0). Which is about 15.7" east and 3.3" north of the center of the UGC 10156 NED01.
