2010CBET.2236....1C

P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that spectroscopic observations of 2010bl (cf. CBET 2233), obtained on Apr. 8 UT by S. Tang 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 2010bl is a normal type-Ia supernova about two weeks past maximum light.
