Wei Gao(Nongan,Jilin,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible nova (mag approximately 17.5) on two 90-s survey images (limiting mag about 19.9)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Dec .03.5573 UT. using an unfiltered CCD ( + 0.5-m f/4 reflector + CCD ). The new object approximately located at R.A. =01h34m01.57s Decl.=+30°42'39".8(equinox 2000.0).Which is about 137.7" east and 182.8" north of the center of the NGC598(M33). Nothing is visible at this position on archival images taken on Dec. 01 (limiting mag 19.9) .
