------ Start for Possible Stand-alone Circular ----
In response to GRB230427 (Swift/BAT trigger 1165948) at 10:31:51 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 98 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 10:13:15.05 = 153.31270
DEC(J2000) = +48:12:14.4 = 48.20400
with a 90%-confidence error radius of about 0.74 arc sec. This position is 1.2
arc sec. from the center of the XRT error circle. The estimated magnitude is
20.31 with a 1-sigma error of about 0.20. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.007.
