GCN Circular 16077
A. A. Breeveld (UCL-MSSL) and C. Pagani (U. Leicester) report on behalf of the Swift/UVOT team: The Swift/UVOT took exposures at both the pointings for GRB140402A described in Pagani et al., GCN Circ. 16075. No optical afterglow consistent with the BAT position given by Cummings (GCN Circ. 16081) is detected in the UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) are: Filter T_start(s) T_stop(s) Exp(s) Mag white 57023 57665 632 >21.5 u 56375 61574 649 >20.5 v 57672 58344 659 >19.8 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.03 in the direction of the burst (Schlegel et al. 1998).
