Supernova 2009ab in UGC 2998.

HARUTYUNYAN A., BENETTI S. and DI FABRIZIO L.

Abstract (from CDS):

A. Harutyunyan, Telescopio Nazionale Galileo (TNG); S. Benetti, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova; and L. Di Fabrizio, TNG, report that a spectrum of 2009ab (cf. CBET 1690), obtained on Feb. 10.83 UT with the 3.5-m TNG (+ DOLORES; range 3500-7800 nm, resolution 1.2 nm), shows it to be that of a type-Ia supernova a few days before maximum light. The best fit to this spectrum found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) is with those of SN 1994D about five days before maximum (Patat et al. 1996, MNRAS 278, 111). Adopting a recession velocity of 3349 km/s (de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies, version 3.9; via NED) for the host galaxy, the expansion velocity, deduced from the Si II 635.5-nm absorption minimum, is about 11100 km/s.
