Supernova 2007rv in NGC 689

G. Folatelli and F. Olivares, University of Chile, on behalf of the Millennium Center for Supernova Studies and Carnegie Supernova Project collaboration, report that a spectrogram (range 350-900 nm) of 2007rv, obtained on Dec. 1.18 UT with the European Southern Observatory 3.6-m telescope (+ EFOSC2) at La Silla, shows this to be a type-Ia supernova about two weeks after maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) provides the best match to SN 1994M at 13 days after maximum light. Adopting the NED recession velocity of 4210 km/s for the host galaxy (from Mathewson and Ford 1996, Ap.J. Suppl. 107, 97), the maximum absorption of the Si II 635.5-nm line indicates an expansion velocity of about 12500 km/s.
