Supernova 2011fm in IC 4815 = PSN J19065017-6141577.

Abstract (from CDS):

N. Morrell, Las Campanas Observatory, Carnegie Supernova Project, reports on a spectrum (range 360-920 nm) of PSN J19065017-6141577 = SN 2011fm obtained on Sept. 1.20 UT with the Las Campanas du Pont 2.5-m telescope (+ WFCCD). Inspection of the data shows that 2011fm is a type-Ia supernova at 2 or 3 weeks past maximum light. Cross-correlation with a library of supernova spectra using the Supernova Identification tool (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) produces a number of good matches with normal type-Ia supernovae between 12 and 20 days after maximum brightness. The minimum of the Si II 635.5-nm absorption is blueshifted by approximately 9800 km/s if the NED recession velocity of 8313 km/s (Kowalski et al. 1987, A.J. 93, 1350) is assumed for IC 4815. Significant Na I absorption (equivalent width 0.22 nm) at the redshift of the host galaxy is observed in the supernova spectrum.
