J. L. Prieto, Carnegie Observatories, reports that optical spectra (range 370-930 nm; resolution 0.7 nm) of 2011I and 2011J were obtained with the APO 3.5-m telescope (+ DIS) on Jan. 13.4 UT. After cross-correlation with a library of supernova spectra using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), they obtain the following spectral classes: 2011I is a normal type-Ia supernova at about 20 days after maximum light; 2011J is a type-Ia supernova around maximum light, with redshift 0.030 ± 0.006 obtained by SNID from the supernova spectral features.
