image paragraph message for exposure 1 of trigger 1131029


THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: unexpected filter, no aspect solution
SRCLIST PROBLEM: no srclist afterglow info, unexpected filter
See notes for more details.

------ Start for Possible Stand-alone Circular ----

In response to GRB221024 (Swift/BAT trigger 1131029) at 13:00:27 UT,

---- UVOT paragraph for Joint or Stand-alone Circular ----

UVOT took a finding chart exposure of 250 seconds with the UVW2 filter starting
127 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 unexpected filter, 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 0.029.
