G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrogram (range 340-740 nm) of 2011aj was obtained on Mar. 2 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 2011aj is a type-Ia supernova a few days past maximum; the velocity of the Si II 635.5-nm feature, measured at the absorption minimum, is 8800 km/s.
