Lluís Galbany (U. Pittsburgh), Jorge Martínez (U. Chile) report/s a classification of object: SN 2017gvr

Type: SN Ib-pec
Redshift: 0.109

Remarks: Using 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.

The following Classification spectrum was provided:
