15983 2023-11-08 11:34:07 Jingyuan Zhao Jingyuan Zhao, Xing Gao (Xingming Obs.) XOSS CV 1 XOSS A classification spectrum of AT 2023wvl was obtained by XOSS. It shows a blue continuum with a series of prominent Balmer absorption lines including Hγ, Hδ, Hε, Hζ and Hη. The spectral characteristics and an outburst amplitude of about 8 mag (above a quiescent level of Vmag=21.3) suggest AT 2023wvl is a dwarf nova . 2023TNSCR2884....1Z
