P. Schady (UCL-MSSL), A.D. Falcone (PSU) report on behalf of the
Swift/UVOT team:
The Swift/UVOT began observing the field of GRB 061110a at 11:48:32 on
2006-11-10 UT, 71s after the BAT trigger (Falcone et al., GCN 5795). No new
source was detected within the XRT error circle (Vetere et al., GCN 5806) or at
the afterglow position reported by Zhai et al. (GCN 5798) 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 3952 2579 20.42
B 4016 442 20.55
U 3888 452 20.28
UVW1 3792 452 19.72
UVM2 6192 1273 20.55
UVW2 4128 452 20.31
------------------------------------------------
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) = 0.09.
