M. H. Siegel (PSU)reports on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 160714A
1682 s after the BAT trigger (Siegel et al., GCN Circ. 19697).
No optical afterglow consistent with the BAT position
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) for the first
finding chart (FC) exposure and subsequent exposures are:
Filter T_start(s) T_stop(s) Exp(s) Mag
white (fc) 1682 1831 147 >20.14
white 1914 8131 292 >21.04
v 1964 8542 293 >19.67
b 1889 7926 293 >20.12
u 1865 7720 490 >20.07
uvw1 1840 2908 293 >20.06
uvw2 1939 8336 235 >20.08
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).
