The Nearby Supernova Factory reports that a spectrum (range 340-1000 nm) of SN 2005az (IAUC #8503), obtained April 4.49 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows it to be a Type Ib near peak brightness. Si II 635.5 nm is well developed and slightly stronger than the He I 587.6 nm line. Na I D lines are present due to both the host and our own galaxy suggesting some extinction along the line of sight to the supernova.
