DLT40

SN Ic

Add

DLT40

Further Gemini-N/GMOS spectroscopy indicates that this is a Type Ic supernova shortly before maximum. Both GELATO and SNID suggests an object very similar to SN 1994I.

DLT40

SN IIb

Add

DLT40

While the lightcurve and comparisons with SNID (Blondin & Tonry 2007) and GELATO indicates this is likely a IIb, other types of stripped envelope SNe were not definitively ruled out.
