S. B. Pandey (UCL-MSSL) and C. B. Markwardt (GSFC/UMD) report on behalf of
the Swift-UVOT team:
The Swift UVOT began observing the GRB 060929 field (trigger 231702), 78
seconds after the BAT trigger (GCN 5654, 5660). No new source was detected
in the co-added UVOT observations down to the following 3-sigma magnitude
upper limits within the refined XRT error circle (GCN 5663):
Filter T_range (s) Exposure (s) 3sigma UL
V 78 - 2356 950 20.71
B 678 - 2295 136 20.55
U 654 - 2271 156 20.25
W1 630 - 2247 156 19.60
M2 606 - 2223 156 19.83
W2 707 - 2333 156 19.98
White 95 - 2309 273 20.96
T_range is calculated from the time of the burst. The upper limits
are not corrected for Galactic extinction E(B-V) = 0.048 along
the line of sight to the burst.
