J. Prieto, Carnegie Observatories; and R. Khan, Ohio State University, report that optical spectra (range 390-740 nm; resolution 1.4 nm) of 2010B (cf. CBET 2115) were obtained with the Hiltner 2.4-m telescope (+ CCDS) at MDM Observatory on Jan. 9.47 UT. The spectrum shows that 2010B is a normal type-Ia supernova at maximum light. After correcting for the recession velocity of the host galaxy (NGC 5370, +3057 km/s; (de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies, ver. 3; via NED) an expansion velocity of 10800 km/s is measured from the absorption minimum of the Si II 635.5-nm feature.
