We report the following classifications from spectroscopic observations with the KAST spectrograph on the Shane telescope obtained on 2021 December 6 UT. The targets were supplied by the Young Supernova Experiment. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name          | IAU Name   | RA (J2000)   | Dec (J2000)  |   z    | Type | Phase | Notes
 
PS21mxv       | AT2021afkm | 01:27:35.21  | +03:29:21.21 | 0.113  |  Ia  | +2d   | (1) 
PS21ndh       | AT2021afra | 21:40:25.82  | +08:18:29.29 | 0.0869 |  Ia  | +6d   | (2) 

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 a Si II velocity of 9,000 km/s. (2) We measure a Si II velocity of 9,500 km/s.
