TITLE: GCN CIRCULAR NUMBER: 42033 SUBJECT: LIGO/Virgo/KAGRA S250830bp: SOAR spectroscopy of two DESGW candidates DATE: 25/09/30 21:11:30 GMT FROM: Hemanth kumar hemanth.bommireddy195@gmail.com

We report on AT2025wzx and AT2025wpo, which were observed by SOAR 2025-09-10T03:10:05 UTC (PI Bommireddy). We clearly see broad Halpha and Hbeta in AT2025wzx, securing its classification as an AGN at z~0.23, thus, we therefore conclude this candidate to be far too distant to be associated with S250830bp (GCN 41607). In contrast, AT2025wpo shows a noisy featureless spectrum, preventing a firm classification.
We thank SOAR Staff for supporting these observations.
