------ Start for Possible Stand-alone Circular ----
In response to GRB180314 (Swift/BAT trigger 814259) at 19:11:31 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150.000 seconds with the White
filter starting 862 seconds after the BAT trigger. No credible afterglow
candidate has been found in the initial data products. Data from the 2.7'x2.7'
sub-image are not available at this time. The 8'x8' region for the list of
sources generated on-board covers 0.00% of the XRT error circle. No correction
has been made for the expected extinction corresponding to E(B-V) of 0.23.
