Immler (NASA/USRA/GSFC) reports on behalf of the Swift/UVOT team:\n\nAnalysis of the merged Swift/UVOT data of GRB 060729 (GCN 5365, 5366,\n5367, 5369) obtained on 2006-07-29 shows that the optical afterglow\nwas detected in the White, V, B, U, UVW1, UVM2, and UVW2 filters.\nThe detection in all of the UVOT bands suggests that the redshift is \nless than\napprox. 1.1. The photometry results are given for the 7 UVOT filters below:\n\nFilter   T_start(s)  Exposure(s)    Mag\n\nWhite     135           726        17.2\nV     115         1,846        17.4\nB     711           461        18.3\nU     686           491        17.3\nUVW1     663           491        17.4\nUVM2     640           306        17.7\nUVW2     730         1,088        18.0\n\nStatistical and systematic errors are 0.1 mag each.\nThe values quoted above are not corrected for the expected\nGalactic extinction of E_{B-V}=0.054 (Schlegel et al. 1998).",
