P. Schady (UCL-MSSL),  A. Moretti (INAF-OAB) report on behalf of the 
Swift/UVOT team:

The Swift/UVOT began observing the field of GRB 060707 at 21:32:24 UT on 
2006-07-07, 126 s after the BAT trigger (Moretti et al., GCN 5285Not found
 
 
). An 
optical counterpart is detected in coadded images in the white, V and 
B-band within the XRT error circle (Guidorzi et al. GCN 5293Not found
 
 
) and 
consistent with the position reported by de Ugarte Postigo et al. (GCN 
5288Not found
 
 
). The photometry results are given for the 7 filters below:
