The nova was clearly detected on '2018-10-13.822' UT using using 6 x 300s frames (1800s 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 17.5±0.04 mag in the CV band (clear visual). We will continue to monitor the nova light curve and strongly encourage additional follow-up observations.
