K. Kinugasa and H. Kawakita, Gunma Astronomical Observatory; and H. Yamaoka, Kyushu University, report that a low-resolution spectrogram (range 390-750 nm) of SN 2004gt, taken on Dec. 17.8 UT with the Gunma 0.65-m telescope (+ GCS), shows He I 587.6-nm absorption prominently, suggesting that it is a type-Ib supernova near maximum light. A W-shaped absorption around 500 nm is also prominent. Adopting the NED recession velocity (1648 km/s), the expansion velocity (deduced from the absorption minimum of He I) is about 12000 km/s.
