We report the independent discovery of a probable nova in M31 on a co-added
630-s R-band CCD frame taken on 2020 Nov. 6.057 UT with the Danish 1.54-m telescope
at La Silla.
The object was independently discovered also by F. Castellani et al. and designated as AT 2020yye.
The object was designated by us as M31N 2020-11c and is located at R.A. = 0h43m13s.15,
Decl. = +41o24'56".0 (equinox 2000.0), which is 324.6" east and 527.5" north 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):
2020 Nov. 5.118 UT, [20.0 (D65); 6.057, 17.55 ± 0.06 (DK154).
This work is based on data collected with the Danish 1.54-m telescope at the ESO
La Silla Observatory.
