In response to GRB230510 (Swift/BAT trigger 1167973) at 12:06:28 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 72 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 21:12:32.89 = 318.13703
DEC(J2000) = +34:26:35.7 = 34.44326
with a 90%-confidence error radius of about 0.65 arc sec. This position is 1.2
arc sec. from the center of the XRT error circle. The estimated magnitude is
19.11 with a 1-sigma error of about 0.16. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.144.
