Jujia Zhang, Jianguo Wang (YNAO), Wenxiong Li, Xiaofeng Wang (THU), Hanjie Tan (CCU), Tianmeng Zhang, Xu Zhou (NAOC) report/s a classification of object: SN 2018pt

Type: SN Ia-91T-like
Redshift: 0.127

Remarks: The spectrum of SN 2018pt matches with the 91T-like type Ia supernova SN 2005eq at t = -4 days relative to the maximum light. Given a redshift of 0.127 (from SNID fit) for its host galaxy, an expansion velocity of about 9300 km/s can be deduced from the Si II 635.5 absorption minimum. Given this redshift (z~0.127) the absolute brightness of this SN is about -20.2 mag.

The following Classification spectrum was provided:
