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 140614A
132 s after the BAT trigger (Page et al., GCN Circ. 16391).
No optical afterglow consistent with the XRT position
(Beardmore et al. GCN Circ. 16393)
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 132 281 147 >21.5
u_FC 290 539 246 >20.5
white 132 763 186 >21.6
v 620 1668 39 >19.1
b 546 739 39 >19.6
u 290 714 265 >20.5
w1 670 1718 39 >19.1
m2 645 1693 39 >18.9
w2 596 783 34 >20.4
The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.12 in the direction of the burst
(Schlegel et al. 1998).
