We report the classification of SN 2021aau with the GMOS spectrograph on the Gemini-South Telescope with GMOS on UT 2022 Jan 21. The target was supplied by DLT40. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name    | IAU Name   | RA (J2000)  | Dec (J2000)  |    z     | Type  |  Phase  | Notes
DLT22b | AT2021aau | 04:45:41.83 | -59:14:43.87 | 0.004440 | II | peak | (1)

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) The red spectrum is consistent with a SN II that suffered significant host-galaxy reddening.
