2010CBET.2232....1C

P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that spectral observations of obtained on Apr. 6 UT by S. Tang with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows 2010bj (cf. CBET 2230) to be a type-II 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 2010bj best matches a type II-P supernova at a phase of maximum light.
