Type Determination for SN 2005ac
Abstract
A spectrum (range 330-990 nm) of SN 2005ac in SDSS J133955.93+005217.1 (Burket and Li, IAUC #8478), obtained on Feb 10.65 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2m telescope, reveals it to be a Type Ia supernova approximately one week past maximum light. The supernova is similar to SN 2001ay (Nugent et al., IAUC #7612), with very strong Si II absorption features throughout the optical spectrum.
