A. Cucchiara (PSU), P. Brown on behalf of the Swift/UVOT
team:

The Swift UVOT began taking data on the field of GRB 060717
222 s after the BAT trigger (Sakamoto et al. 2006,
GCN Circular 5326).  No new source, relative to the DSS, is seen
inside the refined XRT error circle (Capalbi et al. GCN 5331)
The 3-sigma upper limits for the first finding chart
and the coadded images are listed below.

Finding chart:

         Midpoint   Exposure
Filter  Time (s)     (s)          Mag
White     272        100       19.57  3-sigma upper limit (160-650 nm)

Coadded images:

Filter     T_start(s)    T_stop(s)    EXPOSURE (s)    Mag   
White    222             10309               1241              20.85  UL

T_start and T_stop are estimated from the time of the burst.
These upper limits have not been corrected for the estimated Galactic
reddening of E_{B-V} = 0.064 mag (Schlegel et al. 1998).
