We report the discovery of a nova candidate in M31 (ULL-ASTRO-MASTER-11) with the IAC80 telescope and its Camelot2 CCD camera, located at Teide Observatory (Tenerife, Spain). We detected this transient on 2024-10-20 00:09:27 UT in a single 300 sec exposure in the SDSS g' filter at g' = 18.29 +/- 0.09, calibrated using PanSTARRS.
The transient is located at RA = 00:43:03.34, Dec = +41:18:30.03 (J 2000), that is 141.4" N, 214.0"
E (1.0 kpc) from the M31 nucleus.
This transient has also been detected by Mai et al. (XOSS, PSP24Y) on 2024-10-20 12:52:32 UT at a clear magnitude of 17.72 +/- 0.16 and reported to TNS (AT 2024ynw)
These results are based on observations made with the IAC80 telescope operated on the island of Tenerife by the Instituto de Astrofisica de Canarias in the Spanish Observatorio del Teide.
