Markwardt (GSFC/UMD) report on behalf of\nthe Swift-UVOT team:\n\nThe Swift UVOT began observing the GRB 060929 field (trigger 231702), 78\nseconds after the BAT trigger (GCN 5654, 5660). No new source was detected\nin the co-added UVOT observations down to the following 3-sigma magnitude\nupper limits within the refined XRT error circle (GCN 5663):\n\n\nFilter        T_range (s)    Exposure (s)    3sigma UL\n\nV             78  - 2356     950             20.71\nB             678 - 2295     136             20.55\nU             654 - 2271     156             20.25\nW1            630 - 2247     156             19.60\nM2            606 - 2223     156             19.83\nW2            707 - 2333     156             19.98\nWhite         95  - 2309     273             20.96\n\nT_range is calculated from the time of the burst.
