The object was independently discovered and first announced by M. Zhang and X. Gao and designated as PNV J00423071+4121276 = AT 2020uyd. The object was designated by us as M31N 2020-10b and is located at R.A. = 0h42m30s.67, Decl. = +41o21'28".5 (equinox 2000.0), which is 153.8" west and 320.0" 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:
2020 Oct. 2.980 UT, [20.0; 4.733, 18.8 ± 0.2; 5.009, 18.7 ± 0.2; 5.734, 18.5 ± 0.2; 5.887, 18.6 ± 0.2.
