on behalf of the Swift/UVOT team report:
The Swift/UVOT began observing the field of GRB 060211B at
15:56:39 UT on 2006-02-11, approximately 83 s after the BAT
trigger (Mateos et al., GCN 4739). No source is detected in the
refined XRT error circle (Page et al., GCN 4745) in the initial
V finding chart, nor the summed images down to the following
3-sigma magnitude upper limits:
Filter T_range(s) Exp(s) 3sigUL(mag)
V 83-283 200 19.4
V 83-7768 869 20.5
B 290-7213 718 21.4
U 615-6955 301 20.4
UVW1 591-8168 550 20.8
UVM2 567-7972 490 20.8
UVW2 519-7604 278 21.2
White 494-7359 236 20.7
Reported times are in seconds since the BAT trigger.
These magnitudes are uncorrected for the expected
Galactic extinction corresponding to E(B-V) = 0.407.
