We report the discovery of a probable slowly rising nova in M31 on a co-added
810-s R-band CCD frame taken on 2016 Jul. 2.059 UT with the 0.65-m telescope
at Ondrejov. The new object is also visible on three prediscovery images taken
with the same instrumentation.
The object designated PNV J00424043+4108423 is located at R.A. = 0h42m40s.43,
Decl. = +41o08'42".3 (equinox 2000.0), which is 43.9" west and 446.2" 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 May 30.047 UT, [20.6; Jun. 23.986, 20.2 ± 0.3 (prediscovery); 25.050,
20.2 ± 0.4 (prediscovery); 30.970, 19.6 ± 0.25 (prediscovery);
Jul. 2.059, 19.5 ± 0.25; 4.065, 18.9 ± 0.2.
We thank M. Wolf for sharing his observing time on Jul. 4.065 UT.
