We report the discovery of an apparent nova in M31 on a co-added 900-s R-band CCD frame taken on 2015 Nov. 22.718 UT with the 0.65-m telescope at Ondrejov and independently on two 600-s luminance filter CCD frames taken on Nov. 22.756 UT with the 0.20-m telescope at Bromsgrove.

The object designated PNV J00433852+4128026 is located at R.A. = 0h43m38s.52, Decl. = +41o28'02".6 (equinox 2000.0), which is 610.1" east and 714.1" north of the center of M31 (see link to Ondrejov's discovery image below).

The following R-band magnitudes (unless otherwise noted) were obtained:

2015 Nov. 16.691 UT, [20.4; 22.718, 17.6 ± 0.1; 22.756, 17.1 ± 0.15 (unfiltered, R-band magnitudes used from comparison stars).
