Discovery report We report the discovery of a possible Nova at 18.65+-0.18CV on several 30-s survey images (limiting mag about 19.0CV) taken by Xing Gao at Xingming Observatory “#”2 (N89) around 2024 Jul. 31.80722 UT using a unfiltered CCD (+0.5m f/4 reflector). The transient approximately located at RA= 00h42m51.85s, DEC = +41d15m51.2s (equinox 2000.0). Which is about 84.9″ east and 17.3″ south of the center of the NGC224(M31).
Subsequently, We obtained follow-up images through a unfiltered CCD (+0.43-m f/6.8 telescope) of the Alnitak Research Telescope Access (ARTA) program at the Alnitak Remote Observatories (I79), and the candidate is clearly visible on the ARTA images.
