2008CBET.1640....1C

P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group reports that a spectrum (range 320-850 nm) of 2008im (cf. CBET 1635), obtained on Dec. 29 UT by M. Calkins with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ib supernova; cross-correlation with a library of supernova spectra, using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), indicates that 2008im is consistent with other type-Ib supernovae at maximum light. A spectrogram, obtained as above on Dec. 30 UT by P. Berlind, shows 2008io (cf. CBET 1639) to be a type-Ia supernova; cross-correlation with a library of supernova spectra, using the SNID code, indicates that 2008io is a normal type-Ia supernova about 50 days past maximum light.
