S. R. Oates & M. De Pasquale (UCL-MSSL) report on behalf of the Swift/UVOT Team:

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 3754 seconds after the BAT trigger. No credible afterglow candidate
has been found in the initial data products. The 2.7'x2.7' sub-image covers 25%
of the BAT error circle. The typical 3-sigma upper limit has been about 19.6
mag. The 8'x8' region for the list of sources generated on-board covers 100% of
the BAT error circle. The list of sources is typically complete down to about 18
mag. No correction has been made for the expected extinction corresponding to
E(B-V) of 0.40.
