Supernova 2012I = PSN J02582783+0611253.

Abstract (from CDS):

M. Dennefeld, Institut d'Astrophysique de Paris; J. Whitbourne, University of Durham; and S. Benetti, Istituto Nazionale di Astrofisica, report that a spectrum (range 370-730 nm; resolution 0.66 nm) of PSN J02582783+0611253 = SN 2012I was obtained on Jan. 19.76 UT with the Haute-Provence 1.93-m telescope (+ Carelec). Using a library of supernova spectra via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi), they found a best fit with normal type-Ia supernovae a few days after maximum. Allowing for a galaxy redshift of z = 0.022099 (Stein 1996, A.Ap. Suppl. 116, 203; via NED), the expansion velocity measured from the deep Si II 635.5-nm absorption is 9400 km/s.
