D. Milisavljevic and R. Fesen, Dartmouth College, report that low-dispersion optical spectra (range 430-790 nm) of 2010V (cf. CBET 2162) and 2010X (CBET 2166) were obtained with the 2.4-m Hiltner telescope (+ CCDS) at MDM Observatory on Feb. 8.4 UT. Comparison with a library of supernova spectra using the "Supernova Identification" tool (SNID; Blondin and Tonry 2007, ApJ., 666, 1024) shows that the spectrum of 2010V closely matches that of the type-Ia normal supernova 2002bo at approximately 24 days post-maximum light; the spectrum of 2010X resembles the type-Ic supernovae 1994I and 2004aw at a few days before maximum light.
