2004IAUC.8387....2S

M. Salvo, B. Schmidt, and P. Wood, Australian National University (ANU), report that a spectrum (range 400-1000 nm; resolution 1.6 nm), taken with the ANU 2.3-m telescope (+ Double- Beam Spectrograph) at Siding Spring on Aug. 12.72 UT, shows SN 2004dt (cf. IAUC 8386) to be a young type-Ia supernova a few days before maximum light. The photospheric expansion velocity, deduced from the absorption minimum of Si II 635.5-nm, is about 16500 km/s (via adoption of the NED recession velocity for the host galaxy NGC 799).
