F. E. Marshall (NASA/GSFC) and E. Sonbas (NASA/GSFC/Adiyaman Univ.)
report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 130514A
97 s after the BAT trigger (Sonbas et al., GCN Circ. 14632).
No optical afterglow consistent with the optical position
from GROND (Schmidl et al. GCN Circ. 14634)
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 97 247 147 >21.3
u_FC 310 560 246 >20.4
white 97 960 281 >21.5
v 639 2529 56 >18.7
b 565 757 39 >19.1
u 310 732 265 >20.5
w1 688 708 19 >19.1
w2 2487 2507 19 >19.5
The magnitudes in the table are not corrected for the
Galactic extinction due to the reddening of E(B-V) = 0.23
in the direction of the burst (Schlegel et al. 1998).
