SN IIb

0.0032

The type had been reverted to the initial IIb classification. The current spectrum shows H alpha and He P Cygni profiles at~10000-12000km/s velocity and SNID-SAGE offers good matches to several type IIb spectra at ~redshift of the likely host galaxy.

Good template matches to young Type IIb SNe at the redshift of the host galaxy (0.003185, NED). The spectrum shows H and HeI absorption lines at about 20000km/s supporting the classification.
