M. R. Drout, D. Milisavljevic, E. Berger, N. Sanders, and A. M. Soderberg, Harvard University, report on low-dispersion spectra (range 330-850 nm) taken on Jan. 19 UT with the 6.5-m MMT (+ Blue Channel). PSN J02582783+0611253 = SN 2012I is a type-Ia supernova near maximum light. Comparison with a library of supernova spectra using the "Supernova Identification" tool (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) provides a good match with the normal type-Ia supernova 1994D at four days before maximum. Using the SNID-determined redshift of z = 0.029, the velocity of the Si II 635.5-nm feature is estimated to be approximately 11500 km/s.
