S. R. Oates (UCL-MSSL) & S. McBreen (MPE) report on behalf of the
Swift UVOT team.
The Swift/UVOT began observing the field of GRB 061122 at 14:47:46 UT
on November 22, 2006, around ~7 hours after the INTEGRAL trigger
(Mereghetti et al., GCN 5831). We do not find any source in the
co-added UVOT
observations within the error circle of the XRT (Beardmore et al., GCN
5842).
Following are the 3-sigma magnitude upper limits:
Filter T_start T_end Exposure 3 sigma UL

V 24658 58558 2645 20.69
B 25401 42918 936 20.62
U 25215 42901 1013 20.2
UVW1 25029 59414 1770 19.46
UVM2 24844 58920 2578 20.96
UVW2 24472 58124 2648 21.54
-------------------------------------------
T_start and T_stop are calculated from the time of the burst. The upper
limits are not corrected for Galactic extinction E(B-V) = 0.183 mag.
