2004IAUC.8317....3H - IAU Circ., 8317, 3 (2004/April-0)
HAMANE T., KINUGASA K., KAWAKITA H. and YAMAOKA H.
Abstract (from CDS):
T. Hamane, K. Kinugasa, and H. Kawakita, Gunma Astronomical Observatory (GAO); and H. Yamaoka, Kyushu University, report that a low-resolution spectrum (range 460-660 nm) of SN 2004bd (cf. IAUC 8316), obtained with the GAO 0.65-m telescope (+ GCS) on Apr. 8.5 UT, shows it to be a type-Ia supernova near maximum. The expansion velocity, determined from the Si II 635-nm absorption minimum, is about 9600 km/s.
