Racusin (GSFC) \nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of the ground-detected \nGRB 140529A 65ks after the BAT trigger (Cummings, GCN. Circ. 16340).\nNo optical afterglow consistent with the XRT position \n(Evans et al., GCN Circ. 16342) is detected in the initial UVOT exposures.\nPreliminary 3-sigma upper limits using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial exposures are:\n\nFilter         T_start(s)   T_stop(s)      Exp(s)         Mag\n\nwhite             65040       69412          287         >21.0\nu                 65017       74873         1635         >21.0\n\nThe magnitudes in the table are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 0.13 in the direction of the burst\n(Schlegel et al. 1998).",
