S. Blondin, M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of SN 2006gj (cf. CBET 631, IAUC 8751), obtained on Sept. 20.43 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova around maximum light. Cross-correlation with a library of type-Ia supernova spectra indicates that 2006gj is most similar to SN 1992A (Kirshner et al. 1993, Ap.J. 415, 589) at -1 day from maximum light. Adopting a recession velocity of 8482 km/s for the host galaxy (from Huchra et al. 2007, private communication, in preparation), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 11500 km/s. Also, interstellar Na I D absorption at the redshift of the host galaxy is visible in the spectrum with an equivalent width of 0.2 nm.
