M. Stritzinger, Oskar Klein Centre, Stockholm University, on behalf of the Millennium Center for Supernova Science, reports that he obtained a spectrogram on May 21.2 UT of PSN J10153321-2034060 = SN 2011ic with the Gemini-South telescope (+ GMOS). The spectrum reveals 2011ic to be a type-Ia supernova around a month past maximum. Comparison with a library of supernova spectra using the SNID program (Blondin and Tonry 2007, Ap.J. 666, 1024) provides excellent matches with SN 2002bo between 40 and 50 days past maximum.
