image paragraph message for exposure 1 of trigger 1071765
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.
2 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 GRB210903 (Swift/BAT trigger 1071765) at 13:53:56 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 166 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.
