D. C. Leonard and A. Gal-Yam, California Institute of Technology, report that a preliminarily reduced CCD spectrum (range 580-900 nm) of SN 2005dc (IAUC 8575), obtained on July 28 UT with the Keck I 10-m telescope (+ LRISp), shows it to be a type-Ia supernova, probably within a week of maximum light. The supernova expansion velocity, derived from the minimum of Si II (rest 635.5 nm), and adopting the NED recession velocity of 2204 km/s for the host galaxy (from Koribalski et al. 2004, A.J. 128, 16) is about 12500 km/s.
