Cappellaro, INAF, Napoli; M. T. Botticella, INAF, Teramo; E. Mason, European Southern Observatory (ESO), write that that obtained spectroscopy of three southern supernovae with the ANTU Very Large Telescope (+ Fors2) at ESO on May 25.2 UT under poor weather conditions. Based on the reduced spectra (range 380-920 nm, resolution 1.0 nm), SN 2005br in IC 5084 (IAUC 8516) appears to be a type-Ib SN about 40 days past maximum; the spectrum is very reddened and shows a strong interstellar Na I D absorption with EW about 0.25 nm. SN 2005bs (IAUC 8517) is a normal type-Ia supernova about 30 days past maximum. SN 2005cb in NGC 6753 (IAUC 8530) appears to be a type-Ib/c supernova, similar to SN 1997X (Munari et al. 1998, A.Ap. 333, 159) at about 10 days after maximum.
