We report the spectroscopic observation of TCP J18104219-1534184, which was discovered by Hideo Nishimura and classified as a classical nova by Aydi et al. (ATel #13517).
We obtained a low-resolution spectrum of the object on 2020-02-23.862 (UT) by using the Kyoto Okayama Optical Low-dispersion Spectrograph with an integral field unit (KOOLS-IFU; Matsubayashi et al. 2019) mounted on the 3.8-m Seimei telescope at Okayama Observatory, Kyoto University. The spectrum shows broad Balmer and Fe II emission lines with P Cygni profile. The H-alpha absorption component of P Cygni profile is blue shifted by ~5000 km/s. Na I, O I, and Ca II/Mg II lines are also present in emission. The overall spectrum is that of a classical nova shortly after maximum light, consistent with the conclusion of ATel #13517.
