Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 350-740 nm) of 2008hm (cf. CBET 1586), obtained on Nov. 30.9 UT by W. Peters with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia 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 2008hm is most similar to normal type-Ia supernovae about 6 days before maximum light.
