We report the discovery of another apparent nova in M31 on a co-added 720-s R-band CCD frame taken on 2016 Mar. 6.806 UT with the 0.65-m telescope at Ondrejov. The new object is also visible on several prediscovery images taken with the same instrumentation under worse seeing conditions.

The object designated PNV J00424914+4116401 is located at R.A. = 0h42m49s.14, Decl. = +41o16'40".1 (equinox 2000.0), which is 54.3" east and 31.6" 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 Feb. 7.753 UT, [19.4; 11.737, 18.9 ± 0.7; 12.742, [19.1; 22.789, 18.6 ± 0.5; 26.737, 18.6 ± 0.4; 27.785, 18.7 ± 0.5; Mar. 6.806, 17.9 ± 0.3; 7.753, 18.2 ± 0.3.
