2004IAUC.8350....3M - IAU Circ., 8350, 3 (2004/June-0)
Supernovae 2004bz, 2004ca, 2004cb, 2004cc.
MATHESON T., CHALLIS P., KIRSHNER R. and CALKINS M.
Abstract (from CDS):
Further to IAUC 8338, T. Matheson et al. report that a spectrum (range 340-730 nm) of SN 2004ca, obtained by M. Calkins on June 10.46 UT, shows it to be a type-Ia supernova near maximum spectral-feature age 2 ± 2 days before maximum light). Adopting the NED recession velocity of 5338 km/s for the host galaxy, the supernova expansion velocity is 12800 km/s for Si II (rest 635.5 nm) and 20400 km/s for Ca II (rest 395.1 nm).
