Wang (PMO/TAMU)PTSSSN Ia-pec0.032PTSSThe spectrum shows that is a peculiar type Ia supernova at about a few days before the maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that it matches with SN 2005hk at t = - 3 days.
