Giacomo Terreran report/s a classification of object: SN 2020pjj

Type: SN Ia-pec
Redshift: 0.03

Remarks: The redshift is measured from the narrow features from the host. The relatively prominent carbon features resemble that of SNe Iax (SN 2002cx-like). However, the high velocities of the Si II 635.5 nm feature (-11,800 km/s) makes us favor a Super-Chandrasekhar SN Ia classification. The reported phase is based on the last non-detection.

The following Classification spectrum was provided:
