477352018-12-23 13:25:1417.5VegaMagClear-Other_Other300Mi Zhang and Xing GaoMi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 17.5) on severl 300-s survey images (limiting mag about 20.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Dec. 23.55919 UT using a unfiltered CCD ( + 0.6-m f/8 Ritchey-Chretien telescope ). The transient approximately located at R.A.=00h42m43.80s +41d17'20".8 (equinox 2000.0). Which is about 5.9" west and 72.3" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Dec. 22.50407 UT(limiting mag 20.5).
