2009CBET.1879....2S

J. M. Silverman, M. T. Kandrashoff, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 340-1020 nm), obtained on July 16 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that 2009hl is a normal type-Ia supernova; after removing the host-galaxy recession velocity (14824 km/s; Kochanek et al. 2001, Ap.J. 560, 566), the absorption minimum of the Si II 635.5-nm feature is found to be blue-shifted by about 15700 km/s. Cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin a nd Tonry 2007, Ap.J. 666, 1024) indicates that it is at maximum light.
