THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.

------ Start for Possible Stand-alone Circular ----
In response to GRB231129 (Swift/BAT trigger 1199764) at 05:05:59 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 143 seconds with the U filter starting
332 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. Data 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.
