Flavio Castellani report the observation by F.Castellani, R.Belligoli, V.Andreoli of a PNV (Mag.18.0R +-0.3 - USNOB1 catalogue) in the host galaxy M31 at Monte Baldo Observatory, Ferrara di Monte Baldo, Verona, Italy (A99), in the course of Italian Supernovae Search Project using a 0.40m f/8 Ritchey-Chretien telescope (+ Moravian G4-9000 KAF CCD unfiltered CCD camera). No stellar source is visible at the position of the transient in our past images including reference image dated 04 february 2022. Transient appear 0.7" from the position of AT 2022abzg discovered 2022/11/01.621 by Xingming Observatory Sky Survey (XOSS). Verifing the position using an image by K. Hornoch, scaled and superimposed on our image, the position appear to be the same.
