------ Start for Possible Stand-alone Circular ----
In response to GRB190218 (Swift/BAT trigger 889483) at 08:54:09 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 543 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 18:58:34.92 = 284.64550
DEC(J2000) = -08:14:15.0 = -8.23749
with a 90%-confidence error radius of about 1.10 arc sec. This position is 5.7
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.42. No correction has been made for the expected extinction corresponding to
E(B-V) of 0.26.
