POSSIBLE SUPERNOVA IN NGC 5430

Guoyou Sun(Wenzhou, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China)，report the discovery of a possible supernova (mag approximately 17.2) on several 60-s survey images (limiting mag about 19.5)taken by Xing Gao in Xingming Observation Sky Survey(C42) around Oct. 3.60524 UT using a unfilled CCD Camera ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ). the new object approximately located at R.A. =14h 00m 47s.14 Dec:=+59°20’16”.8 (equinox 2000.0). Nothing was visible at this position on DSS on Apr 8,1997(limiting mag about 19.5).
