Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag approximately 16.9) on three 40-s survey images (limiting mag about 19.2)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Jan. 09.89694; Jan. 14.94532 and 14.94601 UT,2014. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =13h 52m 24s.11 Decl.=+39 41 28.2(equinox 2000.0). Which is about 12.2″ east and 14.1″ north of the center of the NGC 5337.
Nothing is visible at this position on archival images taken on Jan.07,2015. (limiting mag 19.5) or on the DSS(POSS2/UKSTU Red) from Apr. 24,1995(limiting mag about 19.8)
