G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 340-740 nm) of PSN J12130023+2516574 = 2012bi was obtained on Mar. 24 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2012bi is a type-Ia supernova about one week after maximum light. A good fit is found to the template of the normal type=Ia supernova 2004ef at +8 days.
