SN Ia

0.026

There is significant reddening in the direction of the object, correcting for E(B-V) = 0.8 mag gives a spectrum that matches pre-max SNe Ia. The total E(B-V) is uncertain which will likely affect the phase of classification. Redshift is estimated from comparisons with template spectra, classification was done with SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) and Gelato (Harutyunyan et al., 2008, A&A, 488, 383).
