A classification spectrum of AT 2023xni was obtained by XOSS. The overall spectral feature is consistent with the result reported by Claudio Balcon. Our spectrum shows a blue continuum with a series of prominent Balmer absorption lines including Hβ, Hγ, Hδ and Hε. The spectral characteristics suggest AT 2023xni is a dwarf nova .

The spectrum shows a blue continuum with H lines at z=0, H-alpha is not visible, and resembles that of a cataclysmic variable.
