*** WARNING -- no XRT distances are available.
Found 9 entries without IDs and 0 entries that are acceptable afterglow candidates for 1215689_g133.
Acceptable entries have no ID, BAT distance < 210" or XRT distance < 20", and are > 0.8*(80 - 10*(mag-6))" from any bright star
from any bright star and >21.6" from other rejected sources.
Magnitude criteria will be applied later.

image paragraph message for exposure 1 of trigger 1215689
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

------ Start for Possible Stand-alone Circular ----
In response to GRB240216 (Swift/BAT trigger 1215689) at 17:39:59 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 100 seconds with the White filter
starting 101 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 0.555.

THERE IS NO ASPECT SOLUTION for the image data.
Found 9 source(s) in Genie image catalog. Found 9 Genie image source(s) without
IDs. There are 0 good candidate(s) in the Genie image catalog. Good candidates
must be brighter than 19.09 mag. Found 221 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 38% of the
Genie image region.
