Hoversten (PSU) reports on behalf of the Swift UVOT team: UVOT took a finding chart exposure of 150 seconds with the white filter of the field of GRB 110928A starting 3341 seconds after the BAT trigger (Hoversten et al., GCN 12394). No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers none of the XRT error circle. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.03.
