J. Prieto, Carnegie Observatories, reports that optical spectra (range 370-930 nm; resolution 0.7 nm) of 2010ef, 2010eg, and 2010eh were obtained with the APO 3.5-m telescope (+ DIS) on June 15 UT. After cross-correlation with a library of supernova spectra using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), the following spectral classifications were obtained: 2010ef is a normal type-Ia supernova at z = 0.11 (redshift from the supernova spectrum) around maximum light; 2010eg is a type-Ia supernova at z = 0.09 (redshift from the supernova spectrum), also around maximum; and 2010eh looks like a type-Ic supernova at z = 0.020 (redshift of the host galaxy, MCG -01-53-11, from the Sloan Digital Sky Survey) around maximum, although SNID also provides relatively good fits with some type-Ib-supernova templates.
