P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, report spectra (range 320-860 nm) of various SN obtained during Dec. 24-27 UT by P. Challis, S. Gottilla (MMTO.org), and E. Marin (MMTO.org) with the MMT 6.5-m telescope (+ Blue Channel). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) yields the following IDs for the observed supernova. * spectrum of PSN J03055989+0432382 best fits a type Ia supernova at a phase of about a -10 to -7 days before maximum brightness. * spectrum of PSN J12452873+2951040 shows it to be a core collapse SN in very early phase. * spectrum of PSN J14041297-0938168 shows it to be a type IIn at a phase of about 30 days. * spectrum of PSN J01585369+0535254 shows it to be a type Ia normal at phase of about 9 days after maximum brightness. * spectrum of CSS131225:030144-092044 shows it to be a type Ia at maximum brightness. redshift from SN fit is 0.05 * spectrum of TCP J06043671-1237406 shows it to be a type IIn at maximum light. * spectrum of PSN J07325276+2929530 shows it to a type Ia matching sn1991T at +9 days after maximum brightness.
