P. Schady (UCL-MSSL), D.B. Fox (PSU) report on behalf of the
Swift/UVOT team:
The Swift/UVOT began observing the field of GRB 061110b at 22:49:14 on
2006-11-10 UT, ~50 minutes after the BAT trigger (Fox et al., GCN 5800).
No new source was detected within the XRT error circle (Grupe et al., GCN
5811) or at the afterglow position reported by Melandri et al. (GCN 5804)
in coadded images in any filter down to the following 3-sigma magnitude
upper limits:
Filter T_mid (s) Exp. (s) 3-sigma UL
------------------------------------------------
V 12256 1438 20.14
B 19296 2815 21.57
U 18864 2164 21.08
UVW1 18288 1928 20.58

UVW2 13376 1737 20.99
White 15952 2494 21.03
------------------------------------------------
T_mid is the mid time of the coadded exposure with respect to the BAT trigger.
These upper limits are not corrected for Galactic extinction E(B-V) = 0.04.
