15625 2023-09-25 05:30:22 Kenta Taguchi Kenta Taguchi (Kyoto University), Keiichi Maeda (Kyoto University) None CV 1 1 Our spectrum is dominated by a blue continuum, with a potentially weak narrow absorption feature of H beta. In addition to our spectrum, considering a probable past outburst in 2013 (see Related file 1), this object is most likely a CV. 2023TNSCR2385....1T
