Type: SN Ia-pec
Redshift: 0.15

Remarks: The transient is consistent with a Type Ia SN at a redshift of z=0.15 as classified using SNID. we also find additional matches to 91T-like SN, which is consistent with the high luminosity implied by the redshift. We classify the event as Ia-pec as the first three GOTO detections appear to suggest a very fast decline rate, before levelling out. Spectroscopic follow-up is recommended.
