Discovery report

We report the discovery of a possible nova at 18.2CV on several 300-s survey images (limiting mag about 20.5CV) taken by Xing Gao at Xingming Observatory “#”3 (N88) around Aug. 23.80021, 2022 UT using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). The transient approximately located at RA= 00h42m41.43s, DEC = +41d15m44.9s (equinox 2000.0). Which is about 32.6″ west and 23.6″ south of the center of the NGC224 (M31).
Nothing is visible at this position on archival images taken on Aug. 19.74948, 2022 UT (limiting mag about 19.5CV).
