TNS Astronomical Transient Report No. 154172

Date Received (UTC): 2022-08-05 07:14:22

IAU Designation: AT 2022qpg

Coordinates (J2000): RA = 00:44:20.790 (11.086625) DEC = +41:23:11.10 (41.386417)

Discovery date: 2022-08-04 22:53:31.776 (JD=2459796.45384)

Potential host galaxy: M31

Remarks: OMB extragalactic nova monitoring by ISSP collaboration, R.Belligoli, F.Castellani, C.Marangoni, report the discovery of a probable nova in M31. Offset 1091E 425N

Remarks: New transient was clearly detected on '2022-08-04 22:51:02.390' UT using 24x300s 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 16.6±0.5 mag in the CV band (clear visual). Offset 1091E 425N We will continue to monitor the PNV light curve and strongly encourage additional follow-up observations.

Remarks: Last non-detected image on '2022-07-31 22:46:22' UT using 24x300s frames (7200s total) was 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.
