12342017-09-25 17:20:11lgalbanyLluís Galbany (U. Pittsburgh), Jorge Martínez (U. Chile)NoneSN Ib-pec0.109Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find relatively good fits to several Type Ib supernovae around a week before maximum light at a redshift z=0.109, however, none of the fits is able to perfectly fit the shallow He I absorptions. In addition, this supernova has been rising for more than a month already.
