D'Elia (SSDC)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 200529A\n195 s after the BAT trigger (D'Elia et al., GCN Circ. 27845).\nNo optical afterglow consistent with the optical position\n(Malesani et al. GCN Circ. 27846)\nis detected in the initial UVOT exposures.\nPreliminary 3-sigma upper limits using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf.
