We report the discovery of a probable nova in M31 on a co-added 900-s R-band CCD frame taken on 2022 Mar. 7.753 UT with the 0.65-m telescope at Ondrejov.
The object designated PNV J00420894+4106240 is located at R.A. = 0h42m08s.94, Decl. = +41o06'24".0 (equinox 2000.0), which is 399.4" west and 584.5" 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 Feb. 28.754 UT, [19.8; Mar. 7.753, 17.2 ± 0.1.
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.
