G. H. Marion, Harvard-Smithsonian Center for Astrophysics and University of Texas; J. Vinko, University of Szeged; and J. C. Wheeler, University of Texas, report that a spectrum (range 430-1000 nm) of SN 2010iw (cf. CBET 2505) was obtained by S. Rostopchin on Oct. 19 UT with the 9.2-m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2010iw is a peculiar type-Ia supernova near maximum brightness. The spectrum most closely resembles that of SN 2000cx at maximum, but the measured velocity of Si II (635.5 nm) for 2010iw is 10300 km/s, which is much lower than reported for SN 2000cx at this epoch by Li et al. (2003, PASP 115, 453).
