We report the classification of AT 2020add (PS20ec) from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. The target was supplied by YSE (ATel #13330). The observation was made on 2020 January 20 UT. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name         | IAU Name  | RA (J2000)  | Dec (J2000)  |   z   | Type  | Phase  | Notes
PS20ec | AT2020add | 10:20:02.26 | +06:37:54.42 | 0.108 | Ia | 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) We measure an Si II 6355 velocity of -11,500 km/s.
