Discovery certificate for object 2023yij TNS Astronomical Transient Report No. 194448 Date Received (UTC): 2023-11-23 23:19:16 Sender: Mr. Raffaele Belligoli Reporting Group: ISSP Discovery Data Source: None Castellani Flavio report/s the discovery of a new astronomical transient. IAU Designation: AT 2023yij Discoverer internal name: OMB-PNV21 Coordinates (J2000): RA = 00:42:45.870 (10.691125) DEC = +41:21:37.90 (41.360528) Discovery date: 2023-11-23 19:11:12.000 (JD=2460272.2994444) Potential host galaxy: M31 Host redshift: -0.001 Remarks: Flavio Castellani report the discovery by F.Castellani, R.Belligoli,and V.Andreoli of a PNV (Mag. 19.1R +-0.2 – USNOA2 catalogue) in the host galaxy M31 at Monte Baldo Observatory, Ferrara di Monte Baldo, Verona, Italy (A99), in the course of Italian Supernovae Search Project using a 0.40m f/8 Ritchey-Chretien telescope (+ Moravian G4-9000 KAF CCD unfiltered CCD camera). No stellar source is visible at the position of the transient in our past images including reference image dated 2023-11-22 19:05:27 Photometry Discovery (first detection): Discovery date: 2023-11-23 19:11:12.000 Flux: 19.1 ABMag Filter: Clear- Instrument: Other Telescope: Other Last non-detection: Last non-detection date: 2023-11-22 19:05:27 Limiting flux: 19.5 ABMag Filter: Clear- Instrument: Other Telescope: Other Remarks: RC 400mm F8 Osservatorio Monte Baldo Italy Details of the new object can be viewed here: https://www.wis-tns.org/object/2023yij Classification certificate for object 2023yij TNS Classification Report No. 16105 Date Received (UTC): 2023-11-26 19:57:27 Sender: Mr. Claudio Balcon Group: None Claudio Balcon (Belluno A.O. ISSP) report/s a classification of object: AT 2023yij Type: Nova Remarks: The low S/N spectrum resembles that of a Nova. The following Classification spectrum was provided: Obsdate: 2023-11-26 18:09:00 Instrument: Other Telescope: Other Remarks: We obtained the low-resolution spectrum using the FOSC-ES32 spectrograph attached to a 0.41m telescope, in the course of Italian Supernovae Search Project.
