| Discovery report | We report the discovery of a possible Nova at 18.63+-0.14CV on several 120-s survey images (limiting mag about 19.5CV) taken by Xing Gao at Xingming Observatory “#”2 (N89) around 2023 Dec. 05.54617 UT using a unfiltered CCD (+0.5m f/4 reflector). The transient approximately located at RA= 00h42m28.90s, DEC = +41d54m10.0s (equinox 2000.0). Which is about 1855.6″ east and 2281.5″ north of the center of the NGC224(M31). |
