14251 2023-01-16 19:40:30 Kenta Taguchi Kenta Taguchi (Kyoto University), Fang Qiliang (Kyoto University), Miho Kawabata (Kyoto University) None CV 1 Our spectrum is dominated by a blue continuum and shows the narrow emission of H alpha and the weak absorption of H beta. The FWHM of the H alpha line is ~ 14 A or ~ 640 km/s (note: considering the spectral resolution R ~ 500, this line may be more narrow, i.e., we may not be able to have resolved it). From these features, we classify it as a CV. 2023TNSCR.117....1T

Correction for a backward name

In the classification report (ID 14251), "Fang Qiliang" should be "Qiliang Fang". I apologize for the backwardness...
