GRB 141205A: Swift/UVOT Upper Limits

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 et al., GCN Circ. ????).
No optical afterglow consistent with the BAT position
(Markwardt et al. GCN Circ. 17140)
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 initial exposures are:

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).
