srclist paragraph message for exposure 1 of trigger 1259578
------ Start for Possible Stand-alone Circular ----
In response to GRB241010 (Swift/BAT trigger 1259578) at 10:05:14 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 105 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 10:13:31.54 = 153.38141
DEC(J2000) = +11:32:03.4 = 11.53429
with a 90%-confidence error radius of about 0.77 arc sec. This position is 0.6
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.33 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.039.
