TNS - Discovery certificate for object 2023bnl TNS Astronomical Transient Report No. 170740 Date Received (UTC): 2023-02-11 09:26:07 Sender: Mr. Raffaele Belligoli Reporting Group: ISSP Discovery Data Source: None Flavio Castellani report/s the discovery of a new astronomical transient. IAU Designation: AT 2023bnl Discoverer internal name: OMB-PNV20 Coordinates (J2000): RA = 09:56:09.100 (149.037917) DEC = +69:02:44.50 (69.045694) Discovery date: 2023-02-10 20:35:21.000 (JD=2459986.3578819) Potential host galaxy: M81 Remarks: F. Castellani, Verona, Italy reports the discovery by Raffaele Belligoli, Flavio Castellani and Vittorio Andreoli, in the course of the ISSP Italian Supernovae Search Project, of an apparent nova on a co-added 7200sec unfiltered images taken with a Moravian G4-9000 KAF CCD unfiltered, from Monte Baldo Observatory (Ferrara di Monte Baldo, Verona, Italy), using the 0.4m f.8 Ritchey-Chrétien telescope, obtained on 2023 February 10.85788 UT. The new object is located at RA 09 56 09.1 DEC +69 02 44.5 (equinox 2000.0) Apparent magnitude about 18.4 in host Galaxy M81. No stellar source was visible at the position of the transient in our past images including reference image dated 2023 February 9.8979 limit magnitude 19.5 The object was independently discovered by K. Hornoch et. al., designated as PNV J09560893+6902443 on 2023 Feb. 10.934 UT and published on ATEL 15896 on 2023 February ; 05:08 UT CBAT - PNV J09560893+6902443 PNV J09560893+6902443 2023 02 10.934 * 09 56 08.93 +69 02 44.3 18.8 U 192E 71S M81 H 1 ATEL #15896 Discovery of a Probable Nova in M81 K.
