------ Start for Possible Stand-alone Circular ----
In response to GRB191017 (Swift/BAT trigger 929981) at 14:36:06 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 301 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of
the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag.
The 8'x8' region for the list of sources generated on-board covers 100% of the
XRT error circle. The list of sources is typically complete to about 18 mag. No
correction has been made for the expected extinction corresponding to E(B-V) of
0.11.

Found 114246.8 counts in the large background region of 5590.0 pixels or a rate
of 20.438 counts/pixel in a radius of 45.0 arcsec. Based on this background,
the typical 5-sigma UL at a random point in the Genie image is 19.71 mag. for a
4-arcsec aperture.
Found 4965.2 counts in the XRT position region of 200.0 pixels or a rate of
24.826 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is 5.851 +/- 0.477 (1-sigma) cps or
17.86 mag and a range from 17.78 to 17.95 mag. The 3-sigma UL at the XRT
position is 7.281 cps or 17.62 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 19.03 mag.
Found 1 srclist source(s) within 10.0" of the XRT position.
The brightest such source has ra= 245.1216 dec= -73.5399 mag=18.79 sep=4.65".
The closest srclist source has ra= 245.1216 dec= -73.5399 mag=18.79 sep=4.65".
Found 1 Genie source(s) within 10.0" of the XRT position. The brightest such
source has ra= 245.1214 dec= -73.5400 mag=17.76 sep=4.51". The closest Genie
source has ra= 245.1214 dec= -73.5400 mag=17.76 sep=4.51".
Report rejected UVOT sources within 10 arcsec XRT position.
Such sources are usually NOT the afterglow.

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 301 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 16:20:29.13 = 245.12138
DEC(J2000) = -73:32:24.0 = -73.54000
with a 90%-confidence error radius of about 0.62 arc sec. This position is 4.51
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.76 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.11.
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.)
