We report the independent discovery of an apparent nova in M31 on a co-added 1440-s R-band CCD frame taken on 2015 Oct. 31.021 UT with the 0.65-m telescope at Ondrejov. The object was confirmed on a co-added 720-s R-band CCD frame taken on Oct. 31.741 UT with the same instrumentation.

The object first announced and designated PNV J00425773+4108123 by Lick Observatory Supernova Search (LOSS) (see here) is located at R.A. = 0h42m57s.73, Decl. = +41o08'12".0 (equinox 2000.0), which is 151.3" east and 476.5" south of the center of M31 (see link to image below).

The following R-band magnitudes were obtained using the 0.65-m telescope at Ondrejov:

2015 Oct. 26.758 UT, [20.2; 31.021, 19.8 ± 0.25; 31.741, 17.9 ± 0.1.
