SUBJECT: GRB061122: Swift/UVOT Optical Observations

FROM:    Samantha Oates at MSSL  <sro@mssl.ucl.ac.uk>

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.
