J. M. Silverman, S. B. Cenko, J. Choi, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 340-980 nm), obtained on Oct. 1 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that 2010hz (CBET 2462) is a type-Ia supernova; after removal of the host-galaxy recession velocity of 7300 km/s, determined from narrow emission features, the absorption minimum of the Si II 635.5-nm line is found to be blueshifted by about 11400 km/s. Cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2010hz is about one week past maximum brightness. SN 2010ic (CBET 2465) is a type-II supernova with well-developed Balmer lines having P-Cyg profiles; after removal of the host-galaxy recession velocity of 4600 km/s, determined from narrow emission features, the absorption minimum of the H-alpha line is found to be blueshifted by about 9900 km/s. Silverman et al. also confirm the findings of Kasliwal et al. (http://www.astronomerstelegram.org/?read=2862) that SN 2010id (CBET 2467), referred to by Kasliwal et al. as PTF10vdl, is a type-II supernova at the same redshift as its host galaxy, NGC 7483. The emission component of the H-alpha line substantially dominates over the absorption component.
