srclist paragraph message for exposure 2 of trigger 815603



------ Start for Possible Stand-alone Circular ----

In response to GRB180319 (Swift/BAT trigger 815603) at 01:12:11 UT,

---- UVOT paragraph for Joint or Stand-alone Circular ----

UVOT took a finding chart exposure of nominal 250.000 seconds with the U filter
starting 300 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 18:20:22.10 = 275.09209
DEC(J2000) = +07:11:13.9 = 7.18720
with a 90%-confidence error radius of about 1.10 arc sec. This position is 12.1
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.12. No correction has been made for the expected extinction corresponding to
E(B-V) of 0.23.
