G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 340-740 nm) of PSN J17470632+5718047 = SN 2011bd was obtained on Apr. 2 UT by Marion with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2011bd is a type-Ia supernova a few days after maximum light. Using an estimated redshift of z = 0.0281, measured from host-galaxy emission lines, the velocity of the Si II 635.5-nm feature is estimated to be approximately 10400 km/s.
