2010CBET.2475....1M

N. Morrell, Las Campanas Observatory, Carnegie Supernova Project; and I. Botti and P. Lopez, Universidad de Chile, report that they obtained a spectrogram (range 364-920 nm) of 2010ih (cf. CBET 2471), which shows that 2010ih is a type-Ia supernova several days past maximum brightness. Cross- correlation with a library of supernova spectra using the Supernova Identification tool (SNID; Blondin and Tonry, 2007, Ap.J. 666, 1024) suggests for 2010ih an age of 2-3 weeks after maximum light and a redshift of 0.006, best matched to the spectrum of SN 1990N at 18 days past maximum. Morrell adds that NGC2325 has a redshift of 0.007, so that the probability is high that 2010ih is a part of that galaxy.
