report on behalf of the Swift-UVOT team:
The Swift/UVOT observed the field of GRB080123 (trigger #301578)
starting 111 seconds after the BAT trigger (Ukwatta et al. 2008, GCN
Circ. 7203). We do not find any new source in any of the UVOT
single or coadded observations inside the XRT enhanced error
circle (Osborne et al., GCN Circ. 7204).
The XRT position is not covered by the V ,U and B
images.
The 3-sigma upper limits (in the UVOT photometric system,
Breeveld et al., GCN Circ. 6614) are listed:
Filter Tstart Tstop Exp Magnitude

uvw1 651 8022 577 >20.86
uvm2 626 7817 578 >20.70
uvw2 731 14026 1188 >21.56
The values quoted above are not corrected for the expected Galactic
extinction corresponding to a reddening of E_{B-V} = 0.03 mag in the
direction of the burst (Schlegel et al. 1998).
