Kleiser, and A. V. Filippenko, University of California, Berkeley, report that inspection of a CCD spectrum (range 330-1000 nm), obtained on Sept. 19 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that SN 2009ix (CBET 1943) 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 it is near maximum light.
