Supernova 2011fn near NGC 2305 = PSN J06483496-6415545.

MORRELL N.

Abstract (from CDS):

N. Morrell, Las Campanas Observatory, obtained a rather noisy spectrum of PSN J06483496-6415545 = SN 2011fn with the Magellan II telescope (+ LDSS3) on the night of July 28-29. The data show that 2011fn is a supernova, but she was unable to get a decent fit with the SNID software using the redshift of NGC 2305; if one allows a redshift of 0.07, as suggested by SNID, one can find some resasonable matches, but it is difficult to decide between an 'oldish' type-Ia event (say, 1 month past maximum) or a somewhat-younger, broad-lined type-Ic event (about 20 days past maximum), in which case, the discovery would have been well before maximum light. Morrell also notes that, much closer to the supernova position than the NGC 2305 nucleus, there is a 2MASS source (2MASXi J0648305-641559) that might be the host galaxy.
