Abstract:
We report the spectroscopic classification of AT 2020rcq 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 400 s.

SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) gives excellent matches with various Type Ia SN templates well before maximum. It will unfortunately be difficult to follow this young, nearby SN Ia due to observational constraints.
