We report the ZTF detection (ZTF23aaaairl) of the probable nova in M31 AT 2023ax (XM94MZ, PNV J00430924+4117022), that was discovered and reported to TNS by Zhang et al. (XOSS, http://xjltp.china-vo.org/xm94mz.html ). ZTF detected this source on 2023-01-07 03:18:17 UTC (g = 17.478 +/- 0.040) and 2023-01-07 06:20:25 UTC (r = 17.250 +/- 0.046). The last ZTF non detection was on 2022-12-23 04:43:28 UTC (r > 20.548). The ZTF position based on the first two detections is R.A. = 00:43:09.223, Decl. = 41:17:02.21, that is 53.51" N, 280.41" E (1.0 kpc) from the M31 galaxy centre. 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.
