POSSIBLE SUPERNOVA IN NGC 2536
Zhijian Xu(Nanjing,Jiangsu,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 16.3) on one 40-s survey image (limiting mag about 18.0) taken by Xing Gao in Xingming Observation Sky Survey(C42) around Oct.11.93917 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=08h 11m 16s.45 Decl.=+25 10 47.4(equinox 2000.0). Which is about 6.0" east and 1.7" north of the center of the NGC 2536. Nothing is visible at this position on archival images taken on Mar.04(limiting mag 18.5),Mar.31(limiting mag 18.4), or on the DSS from Jan.10,1989(limiting mag about 19.9).
