We report the independent discovery of a probable nova in M31 on a co-added 1620-s R-band CCD frame taken on 2022 Jul. 13.012 UT with the 0.65-m telescope at Ondrejov.
The object was independently discovered on Jul. 14.212 UT by F. Romanov and designated as PNV J00423928+4115169 = AT 2022ouu. The object was designated by us as M31N 2022-07d and is located at R.A. = 0h42m39s.29, Decl. = +41o15'16".7 (equinox 2000.0), which is 56.8" west and 51.8" south of the center of M31 (see link to discovery image below).
The following R-band magnitudes were obtained using the 0.65-m telescope at Ondrejov:
2022 Jul. 12.029 UT, [19.8; 12.937, 19.0 ± 0.3; 13.012, 19.1 ± 0.2;
15.935, 17.1 ± 0.1.
As with all extragalactic novae, follow-up spectroscopic and photometric observations to confirm the nova's nature and determine its spectroscopic class and rate of decline (speed class) are encouraged.
