Raffaele Belligoli report/s the discovery of a new astronomical transient.
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
Photometry
Discovery (first detection):
Discovery date: 2022-08-04 22:53:31.776
Flux: 16.6 STMag
Filter: Clear-
Instrument: Other
Telescope: Other
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.
Last non-detection:
Last non-detection date: 2022-07-31 22:46:22
Limiting flux: 19 STMag
Filter: Clear-
Instrument: Other
Telescope: Other
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. (Latitudine 45° 41' 52" N. Longitudine 10° 51' 32" E)
Archival info: DSS
Remarks: No stellar source is visible at the transient's position in our past images and ALADIN sky atlas. No variable star is present at these coordinates on the SIMBAD database.
