S. Blondin, M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrogram (range 350-740 nm) of SN 2006dq (cf. CBET 576), obtained by P. Berlind on July 18.28 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-II supernova roughly 3 weeks past explosion. The spectrum consists of a blue continuum and P-Cyg lines of the Balmer series, consistent with the plateau phase of a normal type-II supernova. The spectrum is similar to that of the type-II-plateau supernova 2004et at 20 days past explosion. Adopting a recession velocity of 9330 km/s for the host galaxy (from de Vaucouleurs et al. 1991, Third Ref. Cat. of Bright Galaxies, ver. 3.9), the maximum absorption in the H_alpha line (rest 656.3 nm) is blueshifted by roughly 8500 km/s.
