IMAGE PROBLEM: incomplete image,
------ Start for Possible Stand-alone Circular ----
In response to GRB190613 (Swift/BAT trigger 908288) at 04:07:18 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 144 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 12:10:07.01 = 182.52919
DEC(J2000) = +67:14:07.0 = 67.23528
with a 90%-confidence error radius of about 1.10 arc sec. This position is 0.7
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.28. No correction has been made for the expected extinction corresponding to
E(B-V) of 0.02.
