Abstract:
We report the spectroscopic classification of SN 2020qln as a Type Ia supernova.

Observations were carried out on the night of 12 August 2020 using the ALFOSC spectrograph mounted on the 2.56-m Nordic Optical Telescope at Roque de los Muchachos Observatory, La Palma, Spain. The spectrum was obtained with 1-arcsec slit and grism #4 covering the spectral range from 3500-9400 AA. The integration of the spectrum is 450 s.

SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) gives excellent matches with various Type Ia SN templates shortly before/around maximum light.

The Type Ia classification is consistent with the preliminary report 2020TNSCR2341....1P and with the ZTF light curve https://alerce.online/object/ZTF20abptxls.
