J. M. Silverman, I. K. W. Kleiser, C. V. Griffith, and A. V. Filippenko, University of California, Berkeley, report that inspection of a low signal-to-noise ratio CCD spectrum (range 350-1000 nm), obtained on Apr. 15 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that 2010bu is a normal 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 2010bu is within a few days of maximum brightness and is at a redshift of 0.039.
