We report the independent discovery of a probable nova in M31 on a co-added
360-s R-band CCD frame taken in poor conditions on 2021 Jun. 5.015 UT with
the 0.65-m telescope at Ondrejov. Due to bad weather in a following night
we were able to confirm the new object on a co-added 1710-s R-band CCD frame
taken on Jun. 7.043 UT with the same instrumentation.
The object was independently discovered on Jun. 6.8368 UT by M. Zhang and X. Gao
and designated as PNV J00430587+4115480 = AT 2021pap. The object was designated
by us as M31N 2021-06a and is located at R.A. = 0h43m05s.89, Decl. = +41o15'48".2
(equinox 2000.0), which is 243.2" east and 20.3" south 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:
2021 Jun. 3.048 UT, [20.0; 5.015, 18.3 ± 0.2; 7.043, 17.0 ± 0.1.
