M A Tucker, A V Payne, A Do, M E Huber, B J Shappee (IfA UH Manoa) and the ASAS-SN team report/s a classification of object: SN 2019gcd

Type: SN Ia-pec
Redshift: 0.019

Remarks: The overall ionization structure matches Type Ia supernova templates, however, the features towards the red end of the spectrum (> 7000A, e.g., Ca triplet) are stronger than expected considering the SiII absorption. The best match in SNID is SN2006bt, a known peculiar Type Ia supernova (see Foley+ 2010, ApJ).

The following Classification spectrum was provided:

Obsdate: 2019-06-02 13:56:38
