image paragraph message for exposure 2 of trigger 1116221
------ Start for Possible Stand-alone Circular ----
In response to GRB220714 (Swift/BAT trigger 1116221) at 13:58:04 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 3552 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 03:08:20.18 = 47.08409
DEC(J2000) = -19:19:45.3 = -19.32925
with a 90%-confidence error radius of about 0.61 arc sec. This position is 1.5
arc sec. from the center of the XRT error circle. The estimated magnitude is
16.52 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.
