We report the independent discovery of a probable nova in M31 on a co-added
600-s R-band CCD frame taken on 2018 Dec. 3.023 UT with the Danish 1.54-m telescope
at La Silla.
The object was independently discovered also by M. Zhang and X. Gao and designated as AT2018jib.
The object was designated by us as M31N 2018-12a and is located at R.A. = 0h42m40s.64,
Decl. = +41o11'07".8 (equinox 2000.0), which is 41.6" west and 300.7" south of the center of M31
(see link to discovery image below).
The following R-band magnitudes were obtained using the Danish 1.54-m telescope (DK154)
and the 0.65-m telescope at Ondrejov (D65):
2018 Nov. 29.897 UT, [20.0 (D65); Dec. 3.023, 18.4 ± 0.1 (DK154); 4.019, 18.06 ± 0.09 (DK154).
This work is based on data collected with the Danish 1.54-m telescope at the ESO
La Silla Observatory.
