M. Stritzinger, N. Morrell, and G. Folatelli, on behalf of the Carnegie Supernova Project and the Millennium Center for Supernova Studies, report that they obtained a spectrogram (range 380-940 nm) of 2009ab on Feb. 11.2 UT with the 6.5-m Magellan II (Clay) telecope (+ LDSS3). The spectrum of 2009ab shows it to be a type-Ia supernova at maximum. Adopting a host-galaxy recession velocity of 3349 km/s (de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies) for the host galaxy, Si II is measured to be blue-shifted by roughly 11000 km/s.
