image paragraph message for exposure 2 of trigger 1200559
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no aspect solution
SRCLIST PROBLEM: no srclist afterglow info
See notes for more details.
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
------ Start for Possible Stand-alone Circular ----
In response to GRB231204 (Swift/BAT trigger 1200559) at 02:51:51 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 880 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. The 2.7'x2.7' sub-image processing
FAILED because of no aspect solution. Results from the list of sources
generated on-board are not available at this time. No correction has been made
for the large, but uncertain, extinction expected.

Unreliable extinction found for bat position. Unreliable extinction found for
xrt position. XRT position found for Genie image. BAT position found.
UVOT exposure began at MET 723352024.91014 or about 2023:338:03:06:59 UT
No information found about the number of stars in the star catalog for srclist
region.
THERE IS NO ASPECT SOLUTION for the image data.
Found 11 source(s) in Genie image catalog. Found 11 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 20.19 mag. Found 335 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
32% of the Genie image region. The XRT position was OUTSIDE the star catalog
search region. The closest Genie source has ra= 135.7303 dec= -40.2521
mag=17.48 sep=198.16".
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.)
(Magnitudes followed by * have been corrected for exposure.)
