In response to GRB240117 (Swift/BAT trigger 1209371) at 07:57:27 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 100 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 expected extinction corresponding to E(B-V) of 0.405.

THERE IS NO ASPECT SOLUTION for the image data.
Found 31 source(s) in Genie image catalog. Found 31 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 19.98 mag. Found 105 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
13% of the Genie image region. The Genie image is INCOMPLETE with 7294 null

This paragraph is only useful if the XRT position is grossly wrong. There are 3
candidate(s) in the image data with mag < 19.42 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=245.80920
(16:23:14.21), DEC=-15.97696 (-15:58:37.1) (J2000). It has a mag of 18.64. It
