We report the classification of AT2023wl from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope, made on 2023 Jan 20 UT. The target was supplied by ATLAS. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name       | IAU Name | RA (J2000)   | Dec (J2000)  |   z    | Type | Phase | Notes 
ATLAS23axf |  2023wl  | 11:15:47.874 | +00:51:08.93 | 0.0458 |  Ia  |  -6   | (1) 

Notes: The redshift is determined from the host galaxy. (1) We measure an Si II 6355 velocity of -12,500 km/s.

We also report the following multi-band (BVr'i') imaging of AT2023wl with the Nickel 1-m telescope at Lick Observatory. Our PSF photometry is calibrated relative to PS1 photometric standards (Flewelling et al., 2020, ApJS, 251, 7F).
