We report the independent discovery of another probable nova in M31 on a co-added 770-s R-band CCD frame taken on 2022 Aug. 9.008 UT with the 0.65-m telescope at Ondrejov.
The object was independently discovered on Aug. 9.304 UT by F. Romanov and designated as PNV J00420940+4115311 = AT 2022qzf. The object was designated by us as M31N 2022-08c and is located at R.A. = 0h42m09s.42, Decl. = +41o15'30".9 (equinox 2000.0), which is 393.6" west and 37.6" 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 Aug. 7.015 UT, [19.7; 8.108 UT, [19.3; 9.008, 18.3 ± 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.
