In response to GRB230916 (Swift/BAT trigger 1192236) at 03:12:47 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the UVW2 filter starting
175 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 large, but uncertain, extinction expected.
