The uvot region is centered at (86.7668,21.7965) with a roll angle of 268.6
It is square with sides of 2.68 arc min. for an area of 7.17 sq arc min
The BAT error circle is centered at (86.7730,21.7980) with a radius of 3.000 arc min
This is 0.357 arc min from the center of the uvot region
The area of the BAT error circle is 28.27 sq. arc min
The UVOT/BAT overlap is at most 6.71 sq. arc min or 0.24 of the BAT error circle

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

WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
------ Start for Possible Stand-alone Circular ----
In response to GRB240313 (Swift/BAT trigger 1219991) at 22:23:26 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 127 seconds with the White filter
starting 102 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.
