We report the discovery of a probable nova in M31 on a co-added 2160-s R-band
CCD frame taken on 2016 Sep. 27.141 UT with the 0.65-m telescope at Ondrejov.
The new object is barely visible also on a prediscovery frame taken on
Sep. 26.161 UT with the same instrumentation.
The object designated PNV J00421729+4109444 is located at R.A. = 0h42m17s.29,
Decl. = +41o09'44".4 (equinox 2000.0), which is 305.0" west and 384.1" south
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 Sep. 24.884 UT, [21.1; 26.161, 19.6 ± 0.5 (prediscovery);
27.141, 19.1 ± 0.2.
We thank M. Wolf for getting images on Sep. 24.884 UT.
