2011CBET.2697....3M

N. Morrell, Las Campanas Observatory; J. Anderson and F. Forster, Universidad de Chile; and G. Pignata, Universidad Andres Bello, on behalf of the Millennium Center for Supernova Science, report that they have obtained a spectrum (range 420-900 nm) of PSN J18593846-4145558 = SN 2011bo on Mar. 29.4 UT with the Magellan Baade 6.5-m telescope (+ IMACS) at Las Campanas Observatory. The spectrum indicates that 2011bo is a type-Ic supernova around two weeks after maximum; comparison with template spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) provides a close match to that of SN 1991N at twelve days after maximum light.
