After posting on the Central Bureau's unconfirmed-objects webpage, D. D. Balam, Dominion Astrophysical Observatory, National Research Council of Canada; M. L. Graham, Las Cumbres Observatory Global Telescope, University of California at Santa Barbara; and E. Y. Hsiao, Lawrence Berkeley Laboratory, report that a spectrogram (range 385-694 nm, resolution 0.3 nm) of 2011B, obtained on Jan. 8.42 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a type-Ia supernova near maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011B is most similar to the type-Ia supernova 1992bo a few days pre-maximum light.
