Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.22, XRT distances < 14.75",

srclist paragraph message for exposure 2 of trigger 886266
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
------ Start for Possible Stand-alone Circular ----
In response to GRB190128 (Swift/BAT trigger 886266) at 13:54:09 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 4442 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 13:48:12.85 = 207.05354
DEC(J2000) = -63:16:28.8 = -63.27468
with a 90%-confidence error radius of about 1.10 arc sec. This position is 4.8
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.74. No correction has been made for the large, but uncertain, extinction
expected.
