FOLLOW UP

Follow-up: OMB extragalactic nova monitoring by ISSP collaboration, R.Belligoli, F.Castellani, V.Andreoli, reports the discovery of a PNV in M81. The new transient was clearly detected on '2022-03-06 19:50:13.056' UT using 24 x 300s frames (7200s 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 19.5±0.2 mag in the CV band (clear visual). Offset: 41W 241N. We will continue to monitor the nova light curve and strongly encourage additional follow-up observations.
