We report the classification of SN 2021adgz with the GMOS spectrograph on the Gemini-North Telescope with GMOS on UT 2021 Nov 5. The target was supplied by ALeRCE using the ZTF data stream. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy. (1) We measure an H-alpha absorption velocity of -10,800 km/s
