Wyatt DLT40 SN Ia 1 DLT40 Spectral classification was performed with SNID (Blondin and Tonry 2007, ApJ, 666, 1024), with good matches to normal type Ia supernovae roughly two weeks before maximum light, in accordance with the current absolute magnitude of M_V~-16 mag. There is also a clear carbon notch (at CII 6580 Angstroms) in the spectrum. 2018TNSCR.259....1S
