SUPERNOVA 2007rb IN NGC 2889
      J. Sollerman and G. 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.
