Pastorello (INAF-OAPd)Padova-AsiagoSN Ic-BL0.007302Padova-AsiagoWe confirm the classification of R. Leadbeater. The spectrum resembles that of the broad line Type Ic SNe 2002ap and 1997ef about 10-15 days after light curve peak. A fairly good match is also obtained with that of a normal Type Ic event such as SN 2004ew (Taubenberger et al. 2006, MNRAS, 371, 1459) at a slightly earlier phase (3-5 days after maximum). We note that a prominent narrow interstellar Na I doublet is observed in absorption at the host galaxy redshift, with an EW = 3.6 A, suggesting significant line-of-sight reddening. The redshift of NGC 6798 is from Theureau et al. 1998, A&AS, 130, 333.
