The Nearby Supernova Factory reports that a spectrum (range 340-1000 nm) of SN 2005ak (CBET #110), obtained Feb 25.66 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2m telescope, shows it to be a type Ia SN just before maximum light. Assuming a host redshift of z =0.027 from NED and SDSS, the Si II 635.5 nm minimum absorption is at approximately 10,000 km/s.
