Jamison Burke, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Craig Pellegrino report/s a classification of object: SN 2019wli

Type: SN Ia-91T-like
Redshift: 0.023

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to 91T-like SNe Ia around 3 weeks after maximum. We measure the redshift of the host to be 0.023 from the narrow Hα emission feature. Assuming this redshift, we measure Ca II velocities of approximately 11,000 km/s and Si II velocities of approximately 9,000 km/s. Assuming the distance modulus calculated from this redshift, the B-band absolute magnitude roughly coeval with the spectrum is approximately -17.4, consistent with the ~+3-week phase.

The following Classification spectrum was provided:
