Kenta Taguchi (Kyoto University) report/s a classification of object: AT 2023oom
Type: Nova
Remarks: In the spectrum, narrow emission lines of Ha and Hb (whose FWHMs are ~ 440 km/s) are prominent. This object is likely a very slow nova in M31.
The following Classification spectrum was provided:
Obsdate: 2023-09-17 12:28:17
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, Kyoto University. The spectral resolution is ~ 500, and the wavelength coverage is 4100-8500 A.
