We report the independent discovery of a probable nova in M31 on a co-added 1080-s R-band CCD frame taken on 2019 Jan. 27.740 UT with the 0.65-m telescope at Ondrejov and also on a co-added 1200-s unfiltered CCD frame taken on Jan. 28.754 UT with the C11 Edge HD telescope at Chelmsford.
The object was independently discovered by G. Carey and designated as AT2019agt. The object was designated by us as PNV J00422916+4114013 and is located at R.A. = 0h42m29s.16, Decl. = +41o14'01".3 (equinox 2000.0), which is 171.0" west and 127.2" south of the center of M31 (see link to Ondrejov's discovery image below).
The following R-band magnitudes (unless otherwise noted) were obtained:
2019 Jan. 22.753 UT, [20.0; 27.740, 19.6 ± 0.3; 28.754, 18.0 ± 0.2 (unfiltered, R-band magnitudes used from comparison stars).
We thank H. Kucakova and M. Wolf for acquiring images on Jan. 22.753 UT.
