We report the discovery of an apparent nova in M31 on a co-added 630-s R-band CCD frame taken in bad seeing conditions on 2013 June 23.019 UT with the 0.65-m telescope at Ondrejov.

The new object designated PNV J00425987+4120379 is located at R.A. = 0h42m59s.87, Decl. = +41o20'37".9 (equinox 2000.0), which is 175.2" east and 269.4" 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:

2013 June 20.050 UT, [20.2; 23.019, 17.3 +/- 0.15.

We thank H. Kucakova for getting M31 images on June 20.050 UT.
