We report the discovery of a probable nova found during our survey of the central region of M31. The object was discovered on a co-added 990-s R-band CCD frame taken on 2024 Jan. 19.898 UT with the 0.65-m telescope at Ondrejov.
The object designated PNV J00430143+4116167 is located at R.A. = 0h43m01s.43, Decl. = +41o16'16".7 (equinox 2000.0), which is 192.9" east and 8.2" 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 (D65):
Date [UT] | Mag | Err | Filter | Telescope
2024-01-16.807 | >19.7 | | R | D65
2024-01-19.898 | 17.4 | 0.1 | R | D65
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.
