We report the following classification from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2024 Mar 19 UT. The targets were supplied by the Young Supernova Experiment (YSE) and ATLAS. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name         | IAU Name   | RA (J2000)  | Dec (J2000)  |   z   | Type | Phase | Notes
 
ATLAS24edv   | AT2024eor  | 06:46:15.61 | +51:41:17.06 | 0.039 |  Ia  |  -7d  |  (1) 
PS24atk      | AT2024ctl  | 10:18:38.65 | -18:05:58.69 | 0.051 |  Ia  | +16d  |   

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 6355 absorption velocity of -11,000 km/s.
