TNS Classification Report No. 14972 [ 2023TNSCR1232....1T ]
Date Received (UTC): 2023-05-25 11:01:45 Sender: Kenta Taguchi
Group: None
Kenta Taguchi (Kyoto University), Miho Kawabata (University of Hyogo), Anjasha Gangopadhyay (Hiroshima University), Avinash Singh (Hiroshima University), Naoto Kojiguchi (Kyoto University) report/s a classification of object: AT 2023ivk
Type: CV
Remarks: Our spectrum is dominated by a blue continuum with narrow emission lines and the potential Na I D line (e.g., H alpha, H beta, Helium I 6678, He II 4686, and N III 4640). Regardless of the slowly-rising light curves by ATLAS and ZTF, this object is likely a CV from our spectrum.
The following Classification spectrum was provided:
Obsdate: 2023-05-21 16:30:21
Instrument: Other
Telescope: Other
Remarks: We performed the follow-up spectroscopic observation using the KOOLS-IFU attached to the 3.8-m Seimei telescope at Okayama Observatory. The spectral resolution is ~ 500, and the wavelength coverage is 4100-8500 A.
