J. L. Prieto, Princeton University, reports that optical spectra (range 350-960 nm; resolution 0.7 nm) of SN 2011ju, 2011jv, and 2011jw were obtained with the APO 3.5-m telescope (+ DIS) on Jan. 2 UT, showing all to be type-Ia supernovae. After cross-correlation with a library of supernova spectra using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), the following redshifts and approximate phases (in days after maximum light) were obtained: 2011ju, 0.103, -2 days; 2011jv, 0.082, +2 days; 2011jw, 0.049, +26 days.
