We report the independent discovery of a probable nova in M31 on a co-added 2070-s R-band CCD frame taken on 2022 Aug. 6.986 UT with the 0.65-m telescope at Ondrejov.
The object was independently discovered on Aug. 7.284 UT by F. Romanov and designated as PNV J00424712+4117103 = AT 2022qug. The object was designated by us as M31N 2022-08b and is located at R.A. = 0h42m47s.10, Decl. = +41o17'10".0 (equinox 2000.0), which is 31.3" east and 61.5" north 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. 3.953 UT, [20.0; 5.095, 19.1 ± 0.2 (prediscovery); 6.986, 17.5 ± 0.15; 7.015, 17.3 ± 0.15.
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.
