------ Start for Possible Stand-alone Circular ----
In response to GRB180407 (Swift/BAT trigger 823014) at 04:05:18 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 1238 seconds after the BAT trigger. No credible afterglow candidate
has been found in the initial data products. Results 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 100% of the BAT 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 0.02.
