M. Modjaz, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrogram (range 340-710 nm) of SN 2004fd (cf. IAUC 8423), obtained by Modjaz on Nov. 13.33 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph), shows it to be a supernova of type Ia, with a spectral-feature age of about 20 days after B maximum. Adopting the NED recession velocity of 5190 km/s for the host galaxy, the supernova expansion velocity, derived from the minimum of Si II (rest 635.5 nm), is 9000 km/s.
