Leloudas, Dark Cosmology Center, Niels Bohr Institute, Copenhagen University, report on spectroscopy of 2007rb (cf. CBET 1140) obtained with the Nordic Optical Telescope (+ ALFOSC; range 350-900 nm, resolution 0.8 nm) on Nov. 16.2 UT. Cross-correlation of the fully reduced spectrum with a library of supernova spectra using the "Supernova Identification" (SNID) code (Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2007rb is a type-Ib/c supernova several weeks past maximum.
