The Swift/UVOT began observing the field of GRB 060108 at 14:40:27 on
2006-01-08 whilst settling on the target, 76 s after the BAT trigger
(Oates et al., GCN 4443). No new source is detected at the XRT position
(Page et al., GCN 4444) in coadded images with any of the filters down
to the following 3-sigma magnitude upper limits. These values are not
corrected for Galactic extinction; E(B-V) = 0.018.
