srclist paragraph message for exposure 1 of trigger 1054627
------ Start for Possible Stand-alone Circular ----
In response to GRB210610 (Swift/BAT trigger 1054627) at 15:03:43 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 93 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 13:37:07.62 = 204.28174
DEC(J2000) = +14:27:55.0 = 14.46528
with a 90%-confidence error radius of about 0.61 arc sec. This position is 1.4
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.12 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.032.
