------ Start for Possible Stand-alone Circular ----
In response to GRB180314 (Swift/BAT trigger 814129) at 00:43:31 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 166 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 06:37:03.68 = 99.26532
DEC(J2000) = -24:29:46.0 = -24.49612
with a 90%-confidence error radius of about 0.61 arc sec. This position is 0.7
arc sec. from the center of the XRT error circle. The estimated magnitude is
16.27 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.08.
