Lin(THU) tns_2018dx_2458130.2522_BAO-2.16m_Cassegrain.txtObjectTNTSCross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) indicates that this transient is consistent with a type Ia supernova about a few days before maximum light.
