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

4 source(s) near the XRT position were rejected as afterglow candidate(s). See
notes for details.
------ Start for Possible Stand-alone Circular ----
In response to GRB240313 (Swift/BAT trigger 1219905) at 03:45:34 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
332 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 0.250.

THERE IS NO ASPECT SOLUTION for the image data.
Found 23 source(s) in Genie image catalog. 4 source(s) are within 20.0" of the
xrt position. Found 23 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.14 mag. Found 101 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 15% of the Genie image region.
Found 4 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 245.1529 dec= -16.3334 mag=17.03 sep=12.52". The closest Genie
source has ra= 245.1529 dec= -16.3334 mag=17.03 sep=12.52".
This paragraph is only useful if the XRT position is grossly wrong. There are 2
candidate(s) in the image data with mag < 19.58 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=245.17284
(16:20:41.48), DEC=-16.34122 (-16:20:28.4) (J2000). It has a mag of 17.89. It
is 109.7" from the BAT position.
****THIS SOURCE IS OUTSIDE XRT ERROR CIRCLE--USE WITH CAUTION***
UVOT took a finding chart exposure of 250 seconds with the U filter starting

DEC(J2000) = -16:20:28.4 = -16.34122
with a 90%-confidence error radius of about 0.77 arc sec. The estimated
magnitude is 17.89 with a 1-sigma error of about 0.16. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.250.
