ASAS-SN, SCAT

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).
