image paragraph message for exposure 1 of trigger 1405083
------ Start for Possible Stand-alone Circular ----
In response to GRB251018 (Swift/BAT trigger 1405083) at 03:12:02 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 83 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 18:48:10.04 = 282.04183
DEC(J2000) = -37:01:42.2 = -37.02840
with a 90%-confidence error radius of about 0.62 arc sec. This position is 3.1
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.96 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.101.

Found 59 source(s) in Genie image catalog. 1 source(s) are within 10.0" of the
xrt position. Found 8 Genie image source(s) without IDs. There are 1 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.35 mag. Found 442 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 41% of the Genie image region.
All AG candidates sorted by magnitude for the current finding chart.
