Due to star catalog entries marked with *, this is probably NOT the afterglow
These entries are within 4" or brighter than 13 mag
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 18.66, BAT distances < 200",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.

srclist paragraph message for exposure 2 of trigger 937114
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no image afterglow info
SRCLIST PROBLEM: srclist filled telemetry buffer

------ Start for Possible Stand-alone Circular ----
In response to GRB191115 (Swift/BAT trigger 937114) at 11:26:20 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 870 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. Data from the 2.7'x2.7' sub-image are
not available at this time. The 8'x8' region for the list of sources generated
on-board covers 90% of the BAT error circle. The list of sources is typically
complete to about 18 mag. No correction has been made for the expected
extinction corresponding to E(B-V) of 0.19.
