SUMMARY: 0 good candidate(s) found.
Results are questionable because aspect solution FAILED.

image paragraph message for exposure 2 of trigger 1218903
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no aspect solution
SRCLIST PROBLEM: no srclist afterglow info
See notes for more details.
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
3 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 GRB240306 (Swift/BAT trigger 1218903) at 01:10:06 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
339 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.

Unreliable extinction found for bat position. Unreliable extinction found for
xrt position. XRT position found for Genie image. BAT position found.
UVOT exposure began at MET 731380579.90846 or about 2024:066:01:16:14 UT
No information found about the number of stars in the star catalog for srclist
region.
THERE IS NO ASPECT SOLUTION for the image data.
Found 15 source(s) in Genie image catalog. 3 source(s) are within 20.0" of the
xrt position. Found 15 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.09 mag. Found 294 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 49% of the Genie image region.
Found 3 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 299.2894 dec= 35.4333 mag=18.12 sep=6.01". The closest Genie
source has ra= 299.2894 dec= 35.4333 mag=18.12 sep=6.01".
Report rejected UVOT sources within 10 arcsec XRT position.
Such sources are usually NOT the afterglow.
****THIS SOURCE NEAR XRT POSITION WAS REJECTED--USE WITH CAUTION****
UVOT took a finding chart exposure of 250 seconds with the U filter starting
339 seconds after the BAT trigger. There is a candidate afterglow in the
rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 19:57:09.45 = 299.28938
DEC(J2000) = +35:25:60.0 = 35.43333
with a 90%-confidence error radius of about 0.78 arc sec. This position is 6.01
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.12 with a 1-sigma error of about 0.16. No correction has been made for the
large, but uncertain, extinction expected.
All AG candidates sorted by magnitude for the current finding chart.
(U/V/White SRCLIST mags < 17.5/17.5/18.5 are reliable. Mag > 18.5/18.5/19.5 are
not. Others are uncertain.)
(U/V/White Genie image mags < 18.0/18.0/19.0 are reliable. Mag > 19.0/19.0/20.0
are not. Others are uncertain.)
