We report the discovery of a probable nova in M31 on a co-added 600-s R-band CCD frame taken on 2022 Mar. 21.771 UT with the 0.65-m telescope at Ondrejov.
The object designated PNV J00423148+4111511 is located at R.A. = 0h42m31s.48, Decl. = +41o11'51".1 (equinox 2000.0), which is 144.9" west and 257.4" 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:
2022 Mar. 20.780 UT, [19.3; 21.771, 16.5 ± 0.06.
As with all extragalactic novae, follow-up spectroscopic and photometric observations to confirm the nova's nature and determine its spectroscopic class and rate of decline (speed class) are encouraged.
