Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of 2006te (cf. IAUC 8789), obtained on Jan. 9.51 UT by M. Calkins with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova around 2 weeks past maximum light. Cross-correlation with a library of type-Ia supernova spectra indicates that SN 2006te is most similar to SN 1998V (cf. IAUC 6844) at +13 days past maximum. Adopting a recession velocity of 9443 km/s for the host galaxy (from "The Updated Zwicky Catalog", http://tdc-www.harvard.edu/uzc/), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 10500 km/s. Blondin et al. add that a spectrum (range 350-740 nm) of 2007C (cf. CBET 798), obtained on Jan. 9.55 UT by Calkins, shows it to be a type-Ib supernova around maximum light. The spectrum shows conspicuous lines of He I (rest 447.1, 587.6 nm) and is most similar to the type-Ib supernova 1998dt (cf. IAUC 7011) at +4 days past maximum light. Also, interstellar Na I D absorption at the redshift of the host galaxy is visible in the spectrum with an equivalent width of 0.3 nm.
