Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag 17.5 at discovery mag) on two 40-s survey images(limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Jan. 18.90494 and Jan. 19.89860 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. =13h 12m 41s.16 Decl.=+12 36 01.8(equinox 2000.0). Which is about 14.5" east and 2.7" north of the center of the NGC 5020. Nothing is visible at this position on archival images taken on Dec.25,2014.
