28992018-10-15 22:52:09Simon PrenticeS. J. Prentice (QUB)SN Ia-pec0.06The spectrum matches several SNe Ia of varying types around maximum light. Using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), good matches can be found to 2000cx at z=0.054 and 91T-like SN 1999aa at z=0.066. The given redshift of 0.06 is an average between the two and the classification as SN Ia-pec reflects that the two best templates are not normal SNe Ia.
