Parsons (GSFC) report on behalf of the Swift-UVOT team:\n\nUVOT took a finding chart exposure of 100 seconds with the White (160-650\nnm) filter starting 1977 seconds after the BAT trigger.  No afterglow\ncandidate has been found in the initial data products. The overlap of the\nsub-image and the BAT error circle is uncertain at this time. The 8'x8'\nregion for the list of sources generated on-board covers 100% of the\nBAT error circle.  Because of the density of catalogued stars, further\nanalysis is required to report an upper limit for any afterglow in the\nregion. No correction has been made for the extinction of E(B-V)=0.202.",
