There are 60767.902 counts in the bkg source region of 5920.0000 pixels.
Rate in bkg region from 0 to 45 arcsec is 10.265 counts/pixel (5-sig UL in 4" is 19.20 mag) for 1186908_g329
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.20, BAT distances < 210",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
Results are questionable because aspect solution FAILED.

image paragraph message for exposure 2 of trigger 1186908
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

------ Start for Possible Stand-alone Circular ----
In response to GRB230824 (Swift/BAT trigger 1186908) at 02:24:24 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
298 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
expected extinction corresponding to E(B-V) of 0.567.

No information found about the number of stars in the star catalog for srclist

THERE IS NO ASPECT SOLUTION for the image data.
Found 15 source(s) in Genie image catalog. Found 15 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 19.20 mag. Found 177 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
16% of the Genie image region.
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.)
