In response to GRB180224 (Swift/BAT trigger 811561) at 22:21:07 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 85 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 13:30:44.09 = 202.68370
DEC(J2000) = +38:04:44.6 = 38.07906
with a 90%-confidence error radius of about 0.63 arc sec. This position is 1.2
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.94 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.01.

xrt position. Found 3 Genie image source(s) without IDs. There are 1 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.87 mag. Found 48 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 4% of the Genie image region.
Found 1 srclist source(s) within 10.0" of the XRT position.
The brightest such source has ra= 202.6837 dec= 38.0792 mag=19.43 sep=1.56".
The closest srclist source has ra= 202.6837 dec= 38.0792 mag=19.43 sep=1.56".
All AG candidates sorted by magnitude for the current finding chart.
(U/V/White SRCLIST mags < 17.5/17.5/18.5 are reliable. Mag > 18.5/18.5/19.5 are
not. Others are uncertain.)
(U/V/White Genie image mags < 18.0/18.0/19.0 are reliable. Mag > 19.0/19.0/20.0
are not. Others are uncertain.)
