------ Start for Possible Stand-alone Circular ----
In response to GRB190114 (Swift/BAT trigger 883600) at 03:10:49 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 859 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 04:22:10.57 = 65.54403
DEC(J2000) = +02:11:29.3 = 2.19146
with a 90%-confidence error radius of about 0.79 arc sec. This position is 0.6
arc sec. from the center of the XRT error circle. The estimated magnitude is
19.52 with a 1-sigma error of about 0.17. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.22.
