M. M. Chester (PSU), F. E. Marshall (NASA/GSFC), and
R. L. C. Starling (U.Leicester) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 141205A
23934 s after the BAT trigger (Cummings, GCN Circ. 17137).
No new sources are detected within the refined BAT error circle
(Markwardt et al. GCN Circ. 17140). Using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373), we find the following
3-sigma upper limits at the center of the BAT error circle:
Filter T_start(s) T_stop(s) Exp(s) Mag
white 23975 28936 837 >21.7
v 24016 29758 826 >20.1
u 23934 28114 837 >20.7
The magnitudes in the table are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.24 in the direction of the burst
(Schlegel et al. 1998).
