Leicester) report on behalf of \nthe Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 141028A\n31037 s after the LAT trigger (Bissaldi et al., GCN Circ. 16969).\nA  fading source is detected in the initial exposures (Siegel and \nPagani, GCN Circ., 16979) in the position given in that circular, also \nconsistent with MASTER (Gorbovsky et a., GCN, Circ 16972), GROND (Graham \net al., GCN Circ. 16977) and the XRT (Pagani, et al., GCN Circ 16986).\n\nPreliminary 3-sigma upper limits using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial \nexposures are:\n\nFilter         T_start(s)   T_stop(s)      Exp(s)         Mag\n\nu                31037        31179          140         19.0+-0.18\nu                69790        72355          2525        20.7+-0.13\nu               105469       127705          4880        21.3+-0.18\n\nThe magnitudes in the table are not corrected for the Galactic \nextinction due to the reddening of E(B-V) = 0.05 in the direction of the \nburst (Schlegel et al. 1998).",
