srclist paragraph message for exposure 1 of trigger 852625
------ Start for Possible Stand-alone Circular ----
In response to GRB180810 (Swift/BAT trigger 852625) at 10:11:22 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150.000 seconds with the White
filter starting 153 seconds after the BAT trigger. There is a candidate
afterglow in the list of sources generated on-board at
RA(J2000) = 09:37:34.86 = 144.39524
DEC(J2000) = -42:48:20.6 = -42.80571
with a 90%-confidence error radius of about 1.10 arc sec. This position is
176.1 arc sec. from the center of the BAT error circle. The estimated magnitude
is 18.13. No correction has been made for the expected extinction corresponding
to E(B-V) of 0.52.
