1171182020-01-28 13:04:091720VegaMagClear-Other_Other300Mi Zhang and Xing GaoMi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 17.0) on several 300-s survey images (limiting mag about 20.0) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Jan. 28.54455 UT using a unfiltered CCD ( + 0.6-m f/8 Ritchey-Chretien telescope ). The transient approximately located at R.A.=00h42m52.32s +41d16'12".8 (equinox 2000.0). Which is about 90.2" east and 4.3" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Jan. 27.67588 UT(limiting mag 19.0). It was suspected the recurrent nova RN M31N 1926-07c.
