2010CBET.2206....1C

P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a low-signal-to-noise-ratio spectral observation, obtained on Mar. 12 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows 2010ak (cf. CBET 2203) to be a type-Ic 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 2010ak best matches a type-Ic supernova at a phase of roughly two weeks past maximum light.
