We report the ZTF detection of the probable nova in M31 AT 2022yax (ZTF22abnrgno) that was discovered by Horti-David, Sarneczky, and Vinko (Konkoly Observatory) and reported to TNS. The ZTF position from a single r-band detection on 2022-10-19 04:43:03 UT is R.A. = 00:43:45.854, Decl. = +41:15:58.61 (equinox 2000.0) and the ZTF r-band magnitude is 19.047 +/- 0.072. We encourage photometric and spectroscopic follow-up observations. Based on Zwicky Transient Facility (ZTF, Bellm et al. 2019) observations processed through the Lasair (Smith, Williams, Young et al. 2019) ALeRCE (Forster et al. 2020) and ANTARES (Matheson et al. 2021) brokers.
