Kenta Taguchi (Kyoto University), Kohki Uno (Kyoto University), Masaki Tsurumi (Kyoto University) report/s a classification of object: AT 2023ufj
Type: NovaRedshift: -0.00137
Remarks: Our spectrum shows prominent P Cygni profiles of H alpha, H beta, and O I 7774. Therefore we propose this object is a nova in M31. Absorption features of Na I D and possible DIBs are seen. Redshift is determined by the peak of H alpha.
The following Classification spectrum was provided:
Obsdate: 2023-10-11 17:14:33
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 of Kyoto University. The spectral resolution is ~ 500, and the wavelength coverage is 4100-8500 A.
