    vsoljの皆様、
    
    木曽観測所のTomo-e Gozenで発見された新天体を分光してみました。

We posted the optical and spectroscopic observations of TCP J20354364+6131329 to ATel: https://www.astronomerstelegram.org/?read=17912
The large outburst amplitude of ~8 mag and the spectral features suggest that this object is a good candidate for a WZ Sge-type dwarf nova. This object is ~14.0 mag now. Follow-up observations are encouraged.
