529382019-02-03 13:03:5918.820.5VegaMagClear-Other_Other300Mi Zhang and Xing GaoMi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 18.8) on severl 300-s survey images (limiting mag about 20.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Feb. 03.54817 UT using a unfiltered CCD ( + 0.6-m f/8 Ritchey-Chretien telescope ). The transient approximately located at R.A.=00h42m51.00s +41d21'03".8 (equinox 2000.0). Which is about 75.3" east and 295.3" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Jan. 29.55427 UT(limiting mag 20.5).
