We report observations of the GW-MMADS sources AT2024hdr and AT2024hdl (GCN #36273) with the WiFES optical spectrograph on the ANU 2.3m telescope.

A weak source is visible near the reported location of AT2024hdl.

We report on the redshifts of the likely host galaxies. 

|    Source | Host Redshift | Comment
| --------- | --------------------------------------------------------------------------------------- 
| 
| AT2024hdl | 0.0416        | Redshift based on weak emission line features          
| AT2024hdr | 0.0659        | AGN features 

The ANU 2.3m telescope is run by the Australian National University
