OMB extragalactic nova monitoring with ISSP collaboration reports the discovery of a probable nova in M31 by F.Castellani, R.Belligoli and C.Marangoni.New transient was clearly detected on '2021-01-26.7209' UT using 16 x 300s frames (4800s total) obtained by a Moravian G4-9000 KAF unfiltered CCD with the 0.4m f.8 Ritchey-Chrétien telescope from Monte Baldo "A.Gelodi" Astronomic Observatory, località Novezzina, Ferrara di Monte Baldo, Verona, Italy. The discovery magnitude is 17.6±0.5 mag in the CV band (clear visual). We will continue to monitor the nova light curve and strongly encourage additional follow-up observations.
