------ Start for Possible Stand-alone Circular ----
In response to GRB190311 (Swift/BAT trigger 892607) at 14:23:33 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 87 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 14:08:15.68 = 212.06532
DEC(J2000) = +53:30:03.0 = 53.50082
with a 90%-confidence error radius of about 0.65 arc sec. This position is 1.7
arc sec. from the center of the XRT error circle. The estimated magnitude is
19.46 with a 1-sigma error of about 0.16. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.01.
