srclist paragraph message for exposure 3 of trigger 1263718
------ Start for Possible Stand-alone Circular ----
In response to GRB241030 (Swift/BAT trigger 1263718) at 05:48:03 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 60 seconds with the White filter
starting 874 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 22:52:33.52 = 343.13967
DEC(J2000) = +80:26:59.4 = 80.44982
with a 90%-confidence error radius of about 0.61 arc sec. This position is 0.6
arc sec. from the center of the XRT error circle. The estimated magnitude is
14.50 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.131.
