------ Start for Possible Stand-alone Circular ----
In response to GRB201229 (Swift/BAT trigger 1015088) at 10:59:30 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 878 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 14:02:45.36 = 210.68902
DEC(J2000) = +48:11:53.3 = 48.19815
with a 90%-confidence error radius of about 0.77 arc sec. This position is 2.0
arc sec. from the center of the XRT error circle. The estimated magnitude is
19.10 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.
