POSSIBLE SUPERNOVA IN NGC 5337 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) NET USNO-A2.0 XM50ZJ C2015 01 09.89694 13 52 24.11 +39 41 28.6 18.1 V C42 XM50ZJ C2015 01 14.94532 13 52 23.99 +39 41 28.6 17.1 V C42 XM50ZJ C2015 01 14.94601 13 52 24.11 +39 41 28.2 16.9 V C42 All images can be seen from: http://www.xjltp.com/XOSS/XM50ZJ/XM50ZJ.htm C42,Xingming Observatory, Mt.

This transient was observed on 2015 01 26.98326 by G. Masi and P. Catalano, 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: 24.08; 28.0 (J2000.0, mean residuals of 0.2" on both axes).
