N. P. M. Kuin (UCL-MSSL) and K. L. Page (U Leicester)
report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140614B
132 s after the BAT trigger (Page et al., GCN Circ. 16394).
No optical afterglow consistent with the XRT position
(Evans et al. GCN Circ. 16395)
is detected in the initial 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 132 282 147 >21.0
u_FC 291 540 246 >20.4
white 132 6723 766 >22.2
v 621 7133 490 >20.1
b 546 6518 471 >20.9
u 291 6314 697 >20.8
w1 670 6108 293 >20.5
m2 1073 7222 298 >20.1
w2 597 6929 471 >21.0
The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.08 in the direction of the burst
(Schlegel et al. 1998).
