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.

This transient was observed on 2014 12 29.96939 by G. Masi, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 16.9 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 03.45; 44.6 (J2000.0, mean residuals of 0.2" on both axes).
