2010CBET.2519....1C

P. Challis and H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that spectroscopy (range 360-760 nm) of 2010ix (cf. CBET 2506), obtained on Oct. 31 UT by M. Calkins with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows that 2010ix is 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 2010ix is a normal type-Ia event at about two weeks past maximum light.
