report on behalf of the Swift-UVOT team:
The Swift/UVOT observed the field of GRB080207 (trigger #302728)
starting 55 sec days after the BAT detection (Racusin et
al. 2008, GCN Circ. 7264). We do not find any new source in any
of the UVOT coadded observations inside the XRT enhanced error
circle (Beardmore et al. 2008, GCN Circ. 7265).
The 3-sigma upper limits (in the UVOT photometric system,
Breeveld et al., GCN Circ. 6614) are listed.

The values quoted above are not corrected for the expected Galactic
extinction corresponding to a reddening of E_{B-V} = 0.02 mag in the
direction of the burst (Schlegel et al. 1998).
