13648 2022-10-19 17:33:17 Tatsuya Nakaoka Tatsuya Nakaoka None SN Ic-BL 0.003 1 A comparison with a library of supernova spectra using GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) reveals that the spectrum gives a good match to broad-lined type Ic supernova, e.g., SN 2007ru at 2-3 weeks after the V band maximum. 2022TNSCR3050....1N
