Kessler, Kavli Institute for Cosmological Physics, Chicago; C. Baltay, D. Rabinowitz, and A. Bauer, Yale University) reports that a spectrum (range 320-1000 nm) of SN 2006D in MCG -01-33-34 (IAUC 8658), obtained Jan. 14.6 UT with the University of Hawaii 2.2-m telescope (+ Supernova Integral Field Spectrograph = SNIFS), reveals that it is a type-Ia supernova about one week prior to maximum. Most striking is the clear signature of C II 657.8-nm. Concomitant features from C II 426.7-, 472.0-, and 723.3-nm are also present. Once the spectrum is corrected for the host redshift (z = 0.008526, Davoust and Contini 2004, A.Ap. 416, 515, via NED), Doppler shifts of the absorption minima of these lines are measured to be around 12000 km/s. Continued observations, including spectropolarimetry, are strongly encouraged of this bright event to follow the evolution of the carbon signature.
