Paul Kuin (MSSL/UCL) reports on behalf of the Swift/UVOT team:
The XRT position of GRB230506B falls on a Gaia DR3 source of magnitude
BP = 19.89, Gmag = 19.34. We see from further analysis of the UVOT data
that within errors the detections are consistent with the Gaia source.
The UVOT data are therefore not the optical afterglow of the GRB.
