Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China),report the discovery of a possible supernova (mag 15.8 at discovery mag) on a 40-s survey image (limiting mag about 19.5)taken by Xing Gao in Xingming
ObservationSky Survey(C42) around Dec. 27.71566 UT, 2014. using an unfilted CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =09h 33m 03s.33 Decl.=+59°40’44”.5
(equinox 2000.0). Which is about 2.6″ west and 2″ south of the center of the anonymous galaxy.Nothing is visible at this position on archival images taken on Dec.25,2014. (limiting mag 19.3) nor on the DSS(POSS2/UKSTU Red) from Feb. 08,1997(limiting mag about 19.8)
