We report the discovery of an apparent nova in M31 on a co-added 1440-s R-band
CCD frame taken on 2016 Aug. 18.999 UT with the 0.65-m telescope at Ondrejov.
The new object is also visible on a prediscovery image taken on Aug. 17.102 UT
with the same instrumentation under poor seeing.
The object designated PNV J00422352+4117197 is located at R.A. = 0h42m23s.52,
Decl. = +41o17'19".7 (equinox 2000.0), which is 234.5" west and 71.2" 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:
2016 Aug. 14.993 UT, [20.2; 17.102, 18.9 ± 0.3; 18.999, 17.5 ± 0.1;
