A. Skielboe, T. Paarup, S. Knudsen, M. Stockman, S. Geier, and J. Fynbo, Niels Bohr Institute, Copenhagen University; together with J. Sollerman and M. Stritzinger, Stockholm University, report that they obtained an optical spectrum of PSN J23013638+3220069 = SN 2011fc with the Nordic Optical Telescope (+ ALFOSC; range 350-900 nm, resolution 0.8 nm) on Aug. 11.13 UT. The spectrum indicates that 2011fc is a type-Ia supernova at a redshift of 0.05. Cross- correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) gives reasonable matches to both normal and subluminous 1991bg-like type-Ia supernovae at roughly a month past maximum.
