Leicester)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT took exposures at both the pointings for GRB140402A \ndescribed in Pagani et al., GCN Circ. 16075. No optical afterglow \nconsistent with the BAT position given by Cummings (GCN Circ. 16081) is \ndetected in the UVOT exposures.\nPreliminary 3-sigma upper limits using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) are:\n\nFilter         T_start(s)   T_stop(s)      Exp(s)         Mag\n\nwhite            57023        57665         632          >21.5\nu                56375        61574         649          >20.5\nv                57672        58344         659          >19.8\n\nThe magnitudes in the table are not corrected for the Galactic \nextinction due to the reddening of E(B-V) = 0.03 in the direction of the \nburst (Schlegel et al. 1998).",
