S. Blondin, M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of 2006oq, obtained on Nov. 21.57 UT by W. Peters with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova around two weeks past maximum light. Cross-correlation with a library of supernova spectra indicates that 2006oq is most similar to the type-Ia supernova 1989B at +14 days from maximum light, at an approximate redshift cz = 6600 ± 1500 km/s. Adopting this recession velocity for the supernova, the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 11000 km/s.
