The Nearby Supernova Factory II (http://snfactory.lbl.gov) reports the following spectroscopic observations of supernovae based on spectra (range 320-1000 nm) obtained with the SuperNova Integral Field Spectrograph (Aldering et al 2002, SPIE, 4836, 61) on the University of Hawaii 2.2-meter telescope. Classifications were performed using Superfit (Howell et al 2002, BAAS, 34, 1256) or SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Heliocentric redshifts listed to two decimal places are measured from supernova features; all others are published values or measured by us from host galaxy features.
