In response to GRB240313 (Swift/BAT trigger 1219989) at 22:09:50 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 47 seconds with the White filter
starting 432 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.
