------ Start for Possible Stand-alone Circular ----
In response to GRB181010 (Swift/BAT trigger 866434) at 05:55:51 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 96 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 03:30:16.89 = 52.57036
DEC(J2000) = -23:02:15.4 = -23.03760
with a 90%-confidence error radius of about 0.78 arc sec. This position is 3.0
arc sec. from the center of the XRT error circle. The estimated magnitude is
19.37 with a 1-sigma error of about 0.16. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.03.

Found 138 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 3% of the srclist region. Found 21 sources in
srclist catalog. Found 0 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
19.22 mag.
Found 3 source(s) in Genie image catalog. 1 source(s) are within 10.0" of the
xrt position. Found 1 Genie image source(s) without IDs. There are 1 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.84 mag. Found 33 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 4% of the Genie image region. The
