PTSS, TNTS

The spectrum is consistent with a subluminous type Ia supernova at a few days after the maximum light. Cross-correlation with a library of supernova spectra using the comparison tool "GELATO" (Harutyunyan et al., 2008, A&A, 488, 383) shows that it mathces with SN 1999by at t = +4.7 days from the maximum light.
