2004IAUC.8307....2M - IAU Circ., 8307, 2 (2004/March-0)
Supernova 2004av in ESO 571-G15.
MATHESON T., CHALLIS P., KIRSHNER R. and BERLIND P.
Abstract (from CDS):
Further to IAUC 8303, T. Matheson et al. report that a spectrum of SN 2004av, obtained by P. Berlind on Mar. 19.31 UT, shows it to be a type-Ia supernova a few days after maximum. Adopting the NED recession velocity of 7057 km/s for the host galaxy, the supernova expansion velocity is 9500 km/s for Si II (rest 635.5 nm). The spectral-feature age of the supernova is 4 ± 2 days after maximum light.
