There is a strong (EW ~ 4.5 A) Na D doublet, indicating significant dust absorption. Dereddening by an appropriate amount to match the Na D absorption strength suggests that the intrinsic SED is quite blue. There is a weak feature close to H alpha. Assuming the feature is H alpha, we measure an expansion velocity of -10,000 km/s. The spectrum is consistent with a young core-collapse SN. Additional observations are needed to determine its precise classification. ATel 12707
