report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 130529A
123 s after the BAT trigger (D'Elia et al., GCN Circ. 14717).
No optical afterglow consistent with the XRT position
(Osborne et al. GCN Circ. 14723)
is detected in the initial UVOT exposures.
Preliminary 3-sigma upper limits using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first
finding chart (FC) exposure and subsequent exposures are:
Filter T_start(s) T_stop(s) Exp(s) Mag
white_FC 123 272 147 >21.6
u_FC 281 530 246 >20.8
white 123 7633 824 >22.1
v 611 12979 1237 >20.8
b 536 19245 1031 >21.1
u 281 18726 1641 >21.5
w1 660 17812 1415 >21.6
m2 635 13481 822 >21.0
w2 587 12064 1275 >21.8
The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.02 in the direction of the burst
(Schlegel et al. 1998).
